Need Of B.Tech Tuitions in Delhi

1. Not taking the course seriously:- After completing the school education, students don’t take the engineering course seriously. They consider it as a simple graduation like B. A (Pass) or B.Com (Pass Course). The reason behind it is the involvement of one or more friends of school time doing B.A or B.Com and enjoying their newly captured college life. Students of Simple graduation courses too much involve themselves in Fresher parties, bunking lectures, strikes in Delhi university etc. When such activites are heard by Engineering students they tend to follow the same in their college also and don’t take studies serious. The best way to avoid such a situation is to join for B.Tech tuitions in Delhi for difficult subjects of first semester like, Maths, Physics and Electrical Technology. Joining tuition gives proactive advantage over the non tuitioners.
2. Too much involvement in college societies:- When you participate in extra curricular activities like, Music, Dance, Stage play etc, you give your precious time of the semester into such waste activities. They don’t count towards you engineering career and most of the students don’t get a better job. If you wanted to be a rock star or an actor, you must have joined some B.A (Pass) type course where you get much of free time. Better optiton is to give your time taking B.Tech tuitions in Delhi for the subjects where you find difficult to understand.
3. Not adjusting psychologically with college environment:- In shool time we have our habits of giving the final exam after one year having only two or three labs per year. In Engineerin course there are more than 12 labs per year and more than 12 theory subjects to clear with same syllabus that of class 12^th The syllabus is undoubtedly lengthy and its is difficult for most of the mediocre type students. It is recommended to them that to join B.tech tuition institutes in Delhi for Maths, Physics, Electrical Technology, Signal system and Digital signal processing, Microcontroller and Microprocessor where it is much difficult to cover in self study.
4. No Interest in the Course:- Students used to take admission in the engineering degree only to fulfill the desire of their parents. Such students have no personal interest in doing such a difficult course. They have a strong desire to be some singer, or musician or an actor.They tend to follow their passion by joining one or more such socities in the college or outside and slowly tend to get away from the studies. When they acquire two more backlog per semester they get trapped in the difficult circumstance and they finally have to leave the course. If such students change their mind after some time they are advised to joing B.Tech tuitions in Delhi from us for most of the difficult subjects.

It is the ending of May and final end term examinations in most of the engineering colleges are over. Reappear students of most of the engineering universities are preparing for the re-examination to be conducted in the mid of June 2017. Many engineering students of Delhi NCR are in search of B Tech Coaching in Delhi for success in reappear examinations. There are very few B.Tech coaching institutes in Delhi and NCR those have made special arrangements for such students. Students have very less time and most of them are studying in far off places like, Chennai, Bangalore, Manipal etc. They are in Delhi NCR in their home for few days of Summer vacations . Most of them are not sure whether enjoy Summer  vacations or prepare for the Reappear examinations. Many of students are not being aware of the specialized B Tech Coaching in Delhi for preparing for such examinations.

searching Google we were able to find B Tech Coaching  in Delhi and relevant faculty there gave study notes and taught the subject in very easy language, my son cleared the subject. So after joining B.Tech tuitions there is sure improvement in the performance of student. It is also worthy to understand that B.Tech is a technical course in which there are lots of mathematical steps and explanations in every topic. Engineering colleges of south have adopted a relatively difficult pattern of questions in final B.Tech exams. Many students of north India are not generally habitual of solving tough question papers. In our opinion the problem with the students of north India origin is not the difficulty level of question paper in fact students of north India have good IQ. There are factors like, not understanding south Indian language or accent, lack of good faculty in south colleges, or less time of self study. It is the reason that students need B.Tech tuitions. There are many coaching institutes providing B Tech Coaching in Delhi, hope you will also be able to find one for your backlog or regular subject.

Are you searching for Engineering tuitios in Delhi for clearing your B.Tech subjects. We provide B.Tech tuitions in Delhi for all subjects and classes. We are located near Subhash Nagar Metro station in New Delhi. If you are a first year student then we recommend you to must join engineering tuitions in Delhi for Physics Chemistry and Maths, in some cases as well as in electrical technology. It is quite clear that most of the students those who study by themselves finds it very difficult to understand the subject clearly, perhabs due to the poor lectures being provided by faculty members of the engineering college. We have found many students to understand the subject very clearly after taking even from first lecture. Engineering tuitions in Delhi are provided for almost all subjects and branches, there can be many options that you can implement in your individual coaching. Parents of some student clearly mention to us that Engineering tuitions in Delhi must include practice session. It is due to the reason that most of the students don’t have time to do practice for subjects like mathematics. Design of Engineering tuitions in Delhi for mathematics is totally based on practice oriented approach. There are many time pass teachers, giving poor quality Engineering tuitions throughout Delhi and NCR. Here in our Academy we have maths faculty with an experience of about 15 years, with IIT Delhi background. You can contact us at 9899927912 for booking a demo lecture.

In such cases student does not speak to his or her parents about the problem and finally yields a backlog in mathematics, which ultimately reduces his or her chances in placements. Engineering tuitions in Delhi for mathematics are specially provided by expert and experienced teachers in easy and friendly language. It is found that students who used to be expert in 11^th and 12^th standards becomes poor and steadily lagging behind in studies. In such cases parents are advised to opt for engineering tuitions in Delhi for difficult subjects where we also motivate the student for engineering education. Many reputed colleges tend to set a difficult paper for engineering subjects in first year. It is done to ensure the quality of students who qualify and promoted to second year. In order to proactively prepare for such difficult examination papers engineering tuitions in Delhi are highly desirable.

Linear integrated circuit is a subject involving study of operational amplifiers and standard ICs like PLL, voltage regulator and function generator. It involves lots of syllabus with detailed numerical and derivations, regular practice and tough level problem solving is must for success in LIC. In colleges like NSIT, examination paper is very tough and lectures are not provided according to final papers. There are very less institutes offering B Tech coaching in Delhi for LIC subject. We provide LIC subject coaching with main focus on tough problem solving and previous examination pattern. We focus on final examination and aim to score high marks in end term examination. LIC also involves puzzle problems of Op amps in which students do not know how to solve a particular op amp circuit and to find the resulting output. Our LIC B Tech coaching  in Delhi involves lots of puzzle circuits of operational amplifier for finding the output. It is also found that there are many questions in final examination of NSIT – LIC paper based on the content not yet given in any book. These concepts are generally discussed by professor in lecture and these are based on research papers and not yet published in books. It is not possible for any ordinary B.Tech coaching institute in Delhi to teach such concepts. We have experience and database of previous notes of professors teaching in NSIT and we have designed specific LIC B.Tech tuition classes in Delhi pertaining to research level problems. You can thus imagine it is a highly demanding and tough subject to clear without any external help.You can attend demo class by calling on our number 9999070890. We also offer B.Tech coaching  in Delhi on individual basis for distant students those are here in Delhi for short time.

In almost all branches engineering mathematics is included in the first year and all students have an opinion of difficulty of mathematics in general. It a fixed trend for almost students to join a B.Tech coaching institute in Delhi. In our opinion engineering mathematics is interesting and a subject that you will enjoy if taught properly. It is not a wonder that last year about 30% engineering students got their backlog alone in engineering mathematics subject. One of the difficulties with the current days coaching students is to find a best out of many B.Tech coaching institutes in Delhi. We are one of them and best in class, we have dedicated faculties helping in every topic and mathematics irrespective of difficulty level. It is the easier and friendly coaching provided by us due to which most of the students tend to join us in every coming semester. You can find many B.Tech coaching institutes in Delhi on places like, Lakshmi nagar, East Delhi Rohini etc. But in west Delhi near subhash nagar metro station we are best among other regional institutes. In recent years education provided by engineering college is degraded at many levels. There is no fault in learning strength of students of engineering as argued by the faculties of prestigious institutes. But it is shear negligence of such faculty members not able to give good results. We are best among the many available B.Tech coaching institutes in Delhi for Mathematics and all other subjects. We offer you to take a demo class from us free of cost then compare with others. We challenge to clear the backlog paper in one attempt only. Call us on number 9899927912 to fix a free demo class.

Digital system design is a core subject included in fifth semester of engineering degree. It included VHDL programming for modeling hardware. There are few B Tech coaching institutes in Delhi for DSD. In most of the colleges in and around Delhi DSD subject is being taught by inexperienced professionals. DSD is an industry oriented subject hence it requires training from an experienced professional. Knowledge of DSD is also helpful in job oriented exams like, GATE, IES and PSU. There are some B Tech coaching institutes in Delhi for DSD located in West near Tilak nagar and Subhash Nagar offering DSD coaching in professional manner. Here they offer DSD coaching using power point slides and professional notes. For university coaching syllabus is strictly followed and major concepts are taught with sufficient examples. It is also worth mentioning that most of the B Tech coaching institutes is Delhi have not developed a professional approach for teaching this subject, DSD is taught theoretically and no practical training is being given. It is very important to give training on software and to encourage the students to do project work on their own. Most of the B Tech coaching institutes in Delhi for subjects like B.Tech Physics, B.Tech Maths, B.Tech Chemistry etc have developed expertise in coaching and guaranteed success is being offered. DSD includes topics like Entity declaration, Architecture body development and Test benches. Subject is very important and every engineering student must take it seriously as a part of their professional industrial carrier.

Most of the government engineering colleges in Delhi have increased their seat intake. Though they have increased seats, but quality of lecture provided is very poor. There is a severe shortage of regular full time faculty members, instead teaching load is being given to guest faculty members. Such teachers have little knowledge of subject and are not teaching according to standards, teaching provided by them is impossible to get understood by any student there. Most of the students in govt. colleges are from Delhi and have good IQ level. But due to poor guidance provided by the guest faculty members many of students have acquired one or more backlog even in first semester. Thus from the start of the second semester there, most of the students are in search of B.Tech tuitions in Delhi. Duration between consecutive sessional examinations is very less as a result students are not able to prepare themselves to solve difficult problems. There is a clear need of B.Tech tuitions in Delhi for subjects like applied physics, electrical technology and applied mathematics. It is found that most of the guest faculty members of govt. colleges set question papers from unsolved problems given at the back of chapters.  It is interesting to note that faculty members themselves are not able to solve such problems. They just copy the questions from back of each chapter and give it in question papers. To fulfill such requirements there is a need of dedicated Academic institute to give training to students. Tejas Engineers Academy is one of such institute located in west Delhi near Meenakshi Garden near Subhash Nagar metro station for providing B.Tech tuitions in Delhi.  Tejas Engineers Academy is having a team of highly experienced faculty members from all departments and ready to provide B.Tech tuitions in Delhi for almost all engineering subject. One of the well known govt. college located in Dwarka has a reputation of giving about 50% backlog in applied mathematics, applied mechanics etc. It clearly shows the frustration level of professors and teachers in govt. colleges. They have clear assurance of govt. job and no threat of anyone and hence they are totally corrupt and have strong inferiority complex by the success of their students. They try to block the degree of students by giving backlog in final year. We also heard the case of a student who got about 22 lakh package in a reputed company and suddenly one of the teacher gave him backlog in lab paper.

To avoid such a situation there is a clear need of B.Tech tuitions in Delhi and we recommend students to take their academic career more seriously. It is quite possible that any one of such teacher having inferiority complex giving backlog to any student. We here at Tejas Engineer Academy assure you to avoid any such situation, we are prepared to give you B.Tech tuitions in Delhi for most difficult subjects like Engineering Mechanics, applied Mathematics, Applied physics etc. We also help you to prepare for the competitive exams like GATE, CAT etc.

When a student get admission into a govt college, he feels himself or herself as a champion that he or she has cleared the all India competition and got a very good rank, suddenly he or she realizes that it is very difficult to clear the examination internally due to clear corruption and inferiority complex of teachers there. Current situation is best described in Bollywod movie Three Idiots.

The post Most Needed – B.Tech Tuitions in Delhi appeared first on B Tech Coaching & Tuitions.

Brief :-

One of the first uses of semiconductor materials was to join a p type material with an n type to form a simple but important semiconductor device called a diode.

The term diode denotes a two electrode device. As semiconductor diode is simply a PN junction with connecting leads or terminals on the two sides of the pn junction. PN junction is also called the crystal diode because the pn junction is grown out of crystal.

Please note In this B Tech coaching lecture we are going to provide you printed notes.

A diode is unidirectional device permitting the easy flow of current in one direction but restraining the flow in opposite direction. A major application of diodes is in rectification i.e. in conversion of ac into dc.

Please note Tejas Engineers Academy is dedicated to provide you all subjects B Tech coaching in Delhi.

Semiconductor diode is becoming more an more popular these days due to its smaller size, cheapness robustness and higher operating efficiency.

We request you to Check for more free lectures of B Tech coaching on our Academy website.

The p type material of the diode is the positive electrode and is called the anode whereas the n type material is the negative electrode and is called the cathode. The arrow symbol used for the anode represents the direction of flow of conventional current. The electron current flows in a direction opposite to the arrow.

The diodes have polarity and therefore, must be connected in circuits in the correct direction. Small diodes are marked with a band to indicate the cathode end. Larger diodes use the diode symbol to indicate the cathode end. Larger diodes use the diode symbol to indicate their polarity.

Please note Analog Electronics is one of the difficult subject for which students used to seek B Tech coaching.

Diodes and transistor numerical problems are covered in Detail here at Tejas Engineers Academy.

Diodes are available in many package configurations, depending on their rating. Small diodes, used for low current application in circuits up to 1 A of average current, are generally packaged in a simple glass or plastic tube. Diodes for handling larger currents are packaged  in metal containers and are often mounted by studs on metal plates to dissipate heat.

Tejas Engineers Academy is having highly experience Analog electronics faculty of experience 12 years. Our faculty will teach you the subject in depth and focus on solving the difficult numerical problems.

Electromagnetic field theory involves problems based on Gauss theorem application, Ampere circuital law, Maxwell equations and electromagnetic waves. Subject of electromagnetic field theory involves double and triple integrals in cylindrical and spherical coordinate systems. Such type of problems are very difficult to understand in self study and currently B.Tech tuitions in Delhi for EMFT is highly in demand. Many student finds it difficult to clear the EMFT subject in final examination. Tejas Engineers Academy offers you expert level B.Tech tuitions in Delhi and our Academy is currently on top amont the available B.Tech coaching institutes in Maths four is a new subject added to the curriculum of GGSIPU. If you are in fourth semester of any branch in ipu then you must be knowing how difficult the subject Maths four is. It involves units of partial differential equations applications, probability, hypothetical testing and linear programming. Linear programming involves simplex and dual simplex methods. Most of B.Tech coaching institutes in Delhi offers you maths four coaching. But they refuse to cover linear programming chapter of simplex method. They skip the topic because of highly difficult and lengthy nature of this chapter. But our Academy is among the few of B.Tech tuition institutes in Delhi which covers all the detailed topics of linear programming of maths four. We offer you free demo class of all subjects mentioned above. You can contact us on 9999070890, 9899927912 to book the class. Thank you.

It is the ending of December and final end term examinations in most of the engineering colleges are over. Reappear students of most of the engineering universities are preparing for the re-examination to be conducted in the mid of January 2016. Many engineering students of Delhi NCR are in search of Engineering tuitions in Delhi for success in reappear examinations. There are very few B.Tech coaching institutes in Delhi and NCR those have made special arrangements for such students. Students have very less time and most of them are studying in far off places like, Chennai, Bangalore, Manipal etc. They are in Delhi NCR in their home for few days of winter vacations. Most of them are not sure whether enjoy winter vacations or prepare for the Reappear examinations. Many of students are not being aware of the specialized Engineering tuitions in Delhi for preparing for such examinations. Sanjay Ahuja who is a father of an engineering student studying in Manipal University said “My son was not aware of Engineering tuitions in Delhi for his backlog subject of VLSI design”. He was finding it very difficult to cover the entire subject in self study because of the difficult language in foreign author book. Earlier he was not able to clear the subject in two attempts. He added, after searching Google we were able to find Engineering tuition in Delhi and relevant faculty there gave study notes and taught the subject in very easy language, my son cleared the subject. So after joining B.Tech tuitions there is sure improvement in the performance of student. It is also worthy to understand that B.Tech is a technical course in which there are lots of mathematical steps and explanations in every topic.

Space charge at a junction

The interface separating the N and P regions is called the metallurgical junction. Let us consider a step junction in which the doping concentration is uniform in each region but there is an abrupt change in doping at the junction. Initially, at the metallurgical junction, there is a very large density gradient in both the electronic and hole concentrations. Majority carrier electrons in the N region will begin diffusing into the P region and majority carrier holes in the p region will begin diffusing into the n region. Fig represents the net positively and negatively charged regions for a semiconductor pn junction where there are not external connection, no applied voltage, no field etc. The net positive and negative charges in the n and p regions induce an electric field near the junction in the direction from the positive to the negative charge, or from the n region to the p region. Since the electrons and holes are both pushed out of the space charge region by the electric field, the region is depleted of any mobile charge and is called the depletion region. Density gradients still exist in the majority carrier concentrations at each edge of the space charge region. A density gradient may be considered as producing a diffusion force acting on the electrons and holes at the edges of the space charge region are indicated in the figure. The electric field in the space charge region develops another force on the electrons and holes which is in the opposite direction to the diffusion force for each type of particle. In thermal equilibrium the diffusion force and the E field force exactly balance each other.

Rahul is an expert teacher for B.Tech Tuition in Delhi. He has written a research paper on space charge at a junction. In following article Rahul sir discusses about the diode and its biasing.

PN Junction as a diode

The essential electrical characteristic of a pn junction is that it constitutes a diode which permits the easy flow of current in one direction but restrains the flow in the opposite direction. We consider now, qualitatively, how this diode action comes about.

Forward biasing

When an external field with p region connected to positive terminal and n region connected to negative terminal of the battery, is applied across the junction, as shown, the junction is said to be forward biased. In this circuit arrangement, the holes on the p side being positively charged particles are repelled from the positive bias terminal and driven towards the junction. Similarly, the electrons on the n side are repelled from the negative bias terminal and driven towards the junction. The result is that the depletion region is reduced in width, and the barrier potential is also reduced. If the applied bias voltage is increased from zero the barrier potential gets progressively smaller and smaller until it effectively disappears and charge carriers can easily flow across the junction. Electronics from the n side are then attracted across to the positive bias terminal on the p side and holes from the p side flow across to negative bias terminal on the ns side. Thus a majority carrier current flows. Since barrier potential is very small a small forward voltage is sufficient to eliminate the barrier completely. Once the barrier is eliminated by the application of forward voltage, junction resistance becomes almost zero and a low resistance path is established in the entire circuit. The current is called the forward current, flow sin the circuit.

There are very less Institutes for B.Tech Tuition in Delhi. Students find it very difficult to understand the working of various types of diodes by themselves. In this article we aim to explain the operations of diode in very easy language. This article will be best for the category of B.Tech coaching Classes in Delhi.

In brief it cannot be said that when the junction is forward biased barrier is reduced and a forward voltage 0.3 v in case of germanium and 0. V in case of silicon is induced. The junction offers low resistance, called the forward resistance Rf to the flow of current and current flows in the circuit due to establishment of low resistance path and the magnitude of current depends upon the magnitude of applied forward voltage.

The mechanism of current flow in a forward biased pn junction is summed up as follows

1. The electrons from the negative bias terminal continue to arrive into the n region while the free electrons in the n region move towards the pn junction.
2. The electrons travel through the n region as free electrons i.e. the current in n region is by free electrons.
3. These free electrons on reaching pn junction, combine with holes and become valence electrons. Since a hole is in the covalent bond and therefore, when a free electron combines with a hole, it becomes a valence electron.
4. The electrons travel through p region as valence electrons and current in this p region is therefore, by holes.
5. These valence electrons, on reaching the left end of the crystal, flow into the positive terminal of the battery.
6. Thus we see that the current in the n type region is due to movement of electrons whereas in the p type region it is carried by the holes. However, in the external circuit i.e. in connecting wires the current is carried by electrons.

There are very less coaching institutes offering B Tech coaching in Delhi for biasing of special purpose diodes.

Reverse applied bias

If an external bias voltage is applied with positive terminal to n side and negative terminal to the p side of a pn junction. In this arrangement electrons from the n side are attracted to the positive bias terminal and holes from p side are attracted to the negative bias terminal. Thus holes from the impurity atoms on the p side of the junction are attracted away from the junction, and the electrons are attracted from the atoms on the n side of the junction. Thus the depletion region is widened, and the barrier potential is increased by the magnitude of the applied bias. With the increased barrier potential, there is no possibility of majority carrier current flow across the junction. Thus the pn junction is in a non conductive state.

In brief it can be said that when the pn junction is reverse biased barrier potential is increased and width of depletion is also increased the junction offers high resistance, called the reverse resistance Rr to the flow of current owing to establishment of high resistance path, very small current called the leakage current or reverse current flows thorough the electric.

Analog Electronics is a core subject Mr. Bhagatveer Singh. He has done B.Tech and M.Tech from Delhi and he is working as a regular faculty in Tejas Engineers Academy and is providing B Tech coaching in Delhi from last 8 years. Following article is provided by Mr. Bhagatveer Singh.

Structure of pn junction

Most semiconductor devices employ one or more PN junction. The PN junction is the control element for the performance of all semiconductor devices such as rectifiers, amplifiers, switching devices, linear and digital integrated circuits. The PN junction is produced by placing a layer of P type semiconductor next to the layer of N type semiconductor. The interface separating the N and P regions is referred to as the metallurgical junction.

The p type semiconductor block has mobile holes and the same number of fixed negative acceptor ions. Similarly the n type semiconductor block has mobile or free electrons and the same number of fixed donor positive ions. Normally the holes, which are the majority charge carriers in p type of material, are uniformly distributed thorough the volume of that material. Similarly the electrons, which are the majority charge carriers in n type of material, are uniformly distributed through the volume of that material. Each region is electrically neutral because each of them carriers equal positive and negative charges.

On the formation of PN junction some of the holes from p type material tend to diffuse across the boundary into n type material and some of the free electrons similarly diffuse into the p type material. This happens due to density gradient (as concentration of holes is higher on p side than that on n side and concentration of electrons is higher on n side than on the p side). This process is known as diffusion.

As a result of the displacement of the charges, an electric field appears across the junction. Equilibrium is established when the field becomes large enough to restrain the process of diffusion. The electric charges are confined to the neighbourhood of the junction and consists of immobile ions. We see that the free electrons crossing the junction create negative ions on the p side by giving some atoms one more electron than their total number of protons. The electrons also leave positive ions behind them on the n side. As negative ions are created on the p side of the junction, the p side acquires a negative potential. Similarly the positive ions are created on the n side and the n side acquires a positive potential. The negative potential on the p side prevents the migration of any more electrons from the n type material to the p type material. Similarly the positive potential on the n side prevents any further migration ofholes across the boundary. Thus, the initial diffusion of charge carriers creates a barrier potential at the junction.

The region around the junction is compleltely ionsed. As a result there are no free electrons on the n side, nor there holes on the p side. Since the region around the junction is depleted of mobile charges it is called the depletion region, the space charge region, or the transition region. The thickness of the depletion region, is of the order of 1 micron.

The variation of electric field constitutes a potential energy barrier against the further diffusion of holes across the barrier.

The necessity for the existence of a potential barrier called the contact, or diffusion potential is now considered further. Under open circuited condtions, the net hole current must be zero. If this statement were not true, the hole densit at one end of the semiconductor would contine to increase indefinitely with time, a situation, which is obviously physically impossible. Sie the concentration of holes in the p side is much greater than that in the n side, a very large diffusion current tends to flow across the junction from the p type material to the n type material. Hence an electric field must build up across the junction in such a direction that a drift current will tend to flow across the untion from the n side to the p side in order to counterbalance the diffusion current. This equilibrium condition of zero resultant hole current allows us to determine the height of the potential barrier in terms of the donor and acceptor concentrations. The magnitude of barrier potential V is of the order of few tenths of a volt.

Barrier voltage depnds on doping density, electronic charge and temperature. For a given junction, the first two factors are fixed, thus making barrier potential dependent on temperature. Increase in temperature creates more minority charge carriers leading to their increased drift across the junction. These extra minority charge carriers reduce the width of the depletion layer equivalent to reduction in potential barrier. It is found that for either silicon or germanium diodes, the barrier potential decreases for each Celsius degree rise.

Tejas Engineers Academy is offering B Tech coaching in Delhi for Differential amplifier circuit. Lecture is scheduled tomorrow. Following is the brief details of the lecture

Differential amplifier circuit configurations:-

The configurations are categorized on the basis of the number of inputs and the way an output voltage is measured. Accordingly, differential amplifier configurations may be classed as follows:

1.      Dual input, balanced output differential amplifier configuration.

2.      Dual input, unbalanced output differential amplifier configuration.

3.      Single input balanced output differential output amplifier configuration.

4.      Single input unbalanced output differential amplifier configuration.

When both the inputs are used the configuration is said to be dual input, otherwise single input. On the other hand, when the output voltage is measured between two collectors, it is referred to as a balanced output, because both collectors C1 and C2 are at the same dc potential w.r.t. ground. In case the output is measured across any one collector w.r.t ground, the configuration is known as an unbalanced output.

Following are the Engineering tuitions in Delhi classes to be held on 30^th July 2015 on Tejas Engineers Academy

Subject:- Analog Electronics – 1

Time: 10 AM to 12 PM

Topics to be covered:- In this lecture we will cover Biasing stabilization of Bipolar Junction Transistor. Topics to be covered are Transistor Modes, Transistor current components, Transistor biasing configuration, Common base, common emitter, common collector and their comparison. Fixed biasing technique, DC load line, AC load line and finding Q-point, Thermal runaway, self biasing with negative feedback. This lecture will be very important if you are a GATE student or a regular engineering student having Analog electronics as the main subject. Transistor is a three terminal semiconductor device having emitter, base and collector regions. A transistor can be of two types, npn or pnp. A transistor needs to be biased before using in amplifier circuit. There are two types of biasing the transistor, fixed biasing and self biasing. In fixed biasing operating point of transistor drifts with change in temperature, this problem is known as thermal runaway. To avoid this problem we use emitter resistant to provide negative feedback. Thermal runaway can also be avoided by using bias compensation.

Subject :- Signals and Systems

Time 12 PM to 2 PM

Topics to be covered and brief explanation:

In this lecture we will cover the system and its properties. A system is a device to which we apply an input signal and as a result it produces some output signal. There can be of two types of systems, continuous time system and discrete time systems. A continuous time systems is that which takes a continuous time signal as its input while discrete time system is that which takes discrete time signal as its input and produced discrete time signal as its output. A system has about six properties. (a) Linearity :- A system is said to be linear if weighted sum of two input signals produces weighted sum of corresponding output signals. (b) Time Invariance:- A system is said to be time invariant if a time shift in the input signal produces equal time shift in the output signal. (c) Causality:- A system is said to be causal if its present output depends upon present or previous values of input only but not on future values. (d) Invertibility:- A system is said to be invertible if we are able to find the value of output signal by the knowledge of input only. (e) Static or Dynamic system:- A system is said to be static or memory less if there is no delay or advanced operation. (f) Stable system:- A system is said to be BIBO stable if a bounded input applied to its input produces bounded output.

Subject : STLD or Digital Electronics, Digital Circuits and systems

Time :- 2 PM to 4 PM

Brief:-

In this lecture we will cover combinational logic circuits design, such as Half Adder, Full Adder, Multiplexers, De-Multiplexer, Decoder, Encoder etc.

A Half Adder is a circuit which is used to add two bits. It produces two outputs, Sum and Carry. Half adder circuit can be realized by taking one exclusive or gate and other and gate. Sum is the xor of both input signals while carry is logic and of both input signals. A Full adder is used to add three bits or information. It has three inputs A, B and C and two outputs Sum and Carry. Sum is the xor of A , B and C while Carry is given by Carry = AB + BC + CA. These equations are determined by first writing the truth table of full adder then solving for Sum and Carry using K – MAP.

The post We provide B Tech Coaching in Delhi appeared first on B Tech Coaching & Tuitions.

This is first week of August in which fresher students of Engineering B.Tech are taking classes. They are finding themselves into a totally different atmosphere of semester system. In school they used to study each and every subject on low pace but here in engineering college study atmosphere is totally different. Here they have more subjects and equal number of labs. Work load is therefore two times and time is almost half as compared to school. Difficulty level is also high as compared to school study. Most of the time students attend lectures in college and prepare lab files. They hardly find time to self study to prepare for the mid semester or sessional exams in week days. On Weekends they relax and avoid self study. It is found that students accumulate the work load of self study till examination dates. They procrastinates the work and put themselves into tough situation to cover a lot of syllabus in very less time. In most of the cases such students accumulate one or more backlogs and slowly head towards disaster. It is thus recommended that engineering student should join a good B.Tech tuition institutes in Delhi. There are a lot of B.Tech tuition institutes in Delhi in West Delhi. One of the excellent B.Tech tuition institutes is Tejas Engineers Academy. It is located near west Delhi near subhash nagar metro station. Here B.Tech tuitions are provided by a team of highly expert college Professors. Faculty of Tejas Engineers Academy has experience of more than 10 years and they are excellent in teaching engineering subjects. If you are searching for a better B.Tech tuition Institutes in Delhi then Tejas Engineers Academy is a clear choice.One of Most difficult subject of first semester engineering is Applied Mathematics -1. Almost all B.Tech tuition Institutes in Delhi provides coaching for this subject. It includes Infinite Series, Successive Differentiation, Leibnitz Theorem, Curve Tracing, Taylor Series, Mc Laurin Series etc. Curve Tracing is one of the challenging subject which most of B.Tech tuition institutes in Delhi are not able to provide a good faculty. Tejas Engineers Academy is having a good Maths faculty with an experience of more than 15 years having M.Tech and Phd from IIT Delhi.  There are some more difficult topics of Applied Mathematics -1 in which most of the B.Tech tuition institutes of Delhi are lacking a good faculty. Come to Tejas Engineers Academy for all you requirements of better coaching of engineering subjects.

Explanation:-

EMAC:- Three phase induction motors and widely used for industrial applications, these are used to drive heavy machines and rotors. They develop torque from three phase windings in which a rotating magnetic field is produced. Rotating magnetic field exists in stator. This magnetic field when acts on the rotator, causes change in magnetic flux and hence eddy currents are produced in rotor. Production of eddy currents causes rotor to move in synchronously with the rotating magnetic field, it is because of the opposing nature of eddy currents due to which they oppose the relative motion.  Its study is very important from the engineering application point of view. Slip is a very important parameter of three phase induction motor. It is defined as the fractional difference is speed of the rotating magnetic field and the rotational speed of rotor.

Signal and system:- Basic signals those are used in engineering study are :- unit step signal, unit impulse signal, unit ramp signal, sinusoidal signal, exponential signal. These signals are used in the analysis and design of various communication engineering blocks. Many operations can be performed on signals, such as time shifting, time reversal, amplitude scaling. Signals can be classified into many types such as even odd signals, deterministic and random signals, periodic and non periodic signals, causal non causal signals. These classification of signals are very important in the study of digital signal processing, communication engineering.

Some of the B.Tech coaching institutes in Delhi provide you schedule of B.Tech coaching classes in Delhi one day before. It is highly convenient to the student if they know class schedule a day before.

Some of the B.Tech coaching institutes in Delhi are not providing the batch coaching to engineering students. Only few institutes have designed batches for almost all universities nearby Delhi. Students of EEE experiences difficulty in finding tuition batches in some of the leading B.Tech coaching institutes in Delhi. Only some of the B.Tech coaching institutes in Delhi are providing batch level coaching for almost all major subjects of EEE.

Some of the B.Tech coaching institutes in Delhi are mixing different universities students together to form a batch in which the desired outcome of course is not obtained with a particular student. Almost no institute is offering separate batch coaching for individual university students. In these batches there only one type of students belonging to one particular university. It gives quality coaching and result oriented program.

In some of the B.Tech courses it is desired to have power point presentation for better explanation and understanding of subject. Some of the B.Tech coaching institutes in Delhi have developed power point presentations for courses they offer you. For selecting a better B. Tech coaching institutes in Delhi keep in mind these parameters. Power point presentation is helping B.Tech coaching institutes in Delhi in a very effective way. It is helping them to increase the efficiency of course and a better understanding of subject.

Consider the subject of VLSI design; it contains a lot of stick diagrams and pictures. Many of the B.Tech coaching institutes in Delhi are teaching VLSI course using power point slides. Ask for the delivery of lectures using Power point presentation it will give you better experience.
