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.

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.

Tejas Engineers Academy is a leading institute providing B.Tech tuitions in Delhi for all major subjects of engineering like Applied Mathematics, Applied Physics, and Engineering Mechanics. Following is the schedule of B.Tech tuitions in Delhi on Tejas Engineers Academy

Explanation:- Hybrid model of BJT is an equivalent circuit of BJT in terms of four h parameters. These parameters are very important for analysis of BJT as an amplifier. Hybrid equivalent circuit of a given amplifier can be formed by first short circuiting all the supply voltages, short circuiting the capacitors and removing the BJT. We then replace the BJT with its equivalent h-model then apply all KVL and KCL laws to find current gain, voltage gain, overall current gain, overall voltage gain, input resistance, output resistance etc.

Latch is a circuit which is used to store one bit memory. Thus latch is also called one bit memory cell. An example of Latch circuit is SR latch. It can be formed by connecting two NOR gates, or two NAND gates with each other. A latch is also called bistable element. When we provide the provision of clock in a latch circuit then it becomes flip flop. Thus flip flop is a latch provided with a clock signal. Example of flip flops are SR, JK, D and T flip flops. Flip flops are characterized by their excitation tables. These are used to design sequential circuits like counters, registers state machines etc.

There are two types of filters in DSP, FIR filters and IIR filters. FIR filter stands for Finite Impulse response filters whereas IIR stands for Infinite Impulse response filters. In DSP every block to which we give some input signal is said to be a filter. The output produced by block depends upon the impulse response of system. Impulse response of system is the output produced by system by giving it a unit impulse as input signal. There is a high demand of B Tech coaching in Delhi for FIR Filter design. There are very special types of FIR filters which are known as Linear Phase FIR filters. These types of Filters have constant group and phase delays. Phase of system is tan^-1(Imaginary Part / Real Part) of Frequency response of system.  Negative differentiation of phase of filter with respect to angular frequency is known as group delay of Filter. Group delay of Filter must be constant for a filter to be linear phase. Research is being done these days to produce linear phase IIR filter. B Tech coaching in Delhi deals with both types of linear phase filters designs i.e. linear phase FIR filters and Linear phase IIR Filters.

We will now describe steps to design FIR filters for which B Tech coaching in Delhi is provided. For Designing Linear phase FIR filters first we should be having a given desired frequency response H_d(e^jw). Then we take its IDTFT to find the time domain version of desired response h_d[n]. We then multiply h_d[n] with a suitable window function w[n]. This gives us filter coefficients h[n]. We then take its Z-Transform to find H(z). Then we draw filter structure in direct form or cascade form. The aim of B Tech coaching in Delhi is to give exposure to Engineering students about various types of Filter design algorithms. Above technique is known as window method of FIR filter design.

There are other techniques also for designing IIR Filters such as Bilinear transformation and Impulse invariance method for which B Tech coaching in Delhi is provided. In next post we will describe various techniques in very easy way for designing IIR filters.

Discrete Fourier Transform is used to convert a discrete time signal from time domain to discrete frequency domain. One of the advantage of DFT is that it gives a finite number of samples in frequency domain, which can easily be stored in memory. On the other hand DTFT gives a continuous spectra which cannot be stored as samples. Disadvantage with DFT is that it requires a lot of additions and multiplications to compute the final result. There are about N² computations done to calculate DFT. There exists an efficient algorithm to compute DFT of a sequence this algorithm is known as Fast Fourier Transform (FFT). Thus Fast Fourier Transform is used to compute DFT of a sequence with less number of additions and multiplications. There are about Nlog₂N computations required to find FFT. Hence number of computations are less to find DFT using FFT. B.Tech tuition institutes in Delhi generally describes each and every details of types of FFT. There are two types of FFT techniques described by B.Tech tuition institutes in Delhi, Decimation in Time (DIT) and Decimation in Frequency (DIF).B.Tech tuition Institutes in Delhi generally provides notes for finding FFT using these techniques. Before computing FFT using DIT, sequence needs to be arranged in the order of bit reversal sequence. Bit reversal order of a sequence is obtained by first converting a sequence positions in binary form, then reading the binary sequence in reverse order for example 6 in binary is 110 when we read it in reverse order it becomes 011 which is 3, hence bit reversal value of 6 is 3. Then the bit reversal sequence is given to a signal flow graph to find the final FFT. In next post we will completely describe the procedure of finding out FFT. Many B.Tech tuition institutes in Delhi do not describe this procedure in detail to students, they tend to focus on mugging the procedure but not able to describe the details and concepts behind the procedure. Tejas Engineers Academy describes you each and every finest detail of the procedure of finding FFT.
