TOPICS OF EACH SUBJECT FROM WHICH MOST OF QUESTIONS WERE ASKED

1)    DIGITAL ELECTRONICS (GATE, MUX,F/F)

2)    MICROPROCESSOR (8085, MICROCONTROLLER) (Q’S ON interrupt structure,rs 232 standard, ppi, 8257, 8259, 8255, memory mapping schemes, icw, ocw)

3)    ANALOG DEVICES (AMPLIFIERS (class a,b,c) OPAMPS (q’s on a/d,d/a converters, differentiator, integration, frequency formulas)

4)    DIGITAL  COMMUNICATIO (Q’S ON FDM AND TAD THEORY BASED)

5)    MICROWAVE (SPACE WAVE  PROPAGATION,ANTENNAS)

6)    CONTROL SYSTEMS (SIMPLE PROBLEMS, QUESTIONS ON FEEDBACK, CONTROLLERS)

7)    SIGNALS  AND SYSTEMS (Q’S ON FOURIER TRANSFORMS, SINC FUNCTIONS, Q’S ON CONVOLUTIONS)

 

QUESTIONS AS FAR AS I REMEMBER CONTROL SYSTEMS Q’S CONTROLLERS, ROUTH STABILITY, FINAL VALUE THEORY, PHASE SHIFTINF OF 1/S^2, Q’s on marginal stability of a system s^5+s^4+----- Q’s on effect of + ve & -ve feedback on stability

DIGITAL ELECTRONICS Q’s mostly on gates, muxes, f/f’s 2 k-map questions, 9’s compliment 0f 19, find out hexadecimal code of… Q’s on encoder, decoder asking no. of active lines Flashing memory is??,q’s on octal to hexadecimal Microprocessor q’s on stack register, instruction pointer, rst 6.5,7,5

Microcontroller: what is interrupt,q’s on interrupt structute, memory mapping schemes,q’s on 8255,8257,8259,rs232 standards

Communications Digital communication: q’s on tdm and fdm etc… how pulse train generated using rectangular pulse q’s on quantiser in pcm why fm is less prone to noise, what is envelope detector,fn’s of limiter in detector of fm cascading lpf and hpf results in… a question : signal limited to 1000khz sampled at nyquist rate,quantized 128, calculate bit rate q’s on optical fibre,total internal reflection networks: 2 q's aspaper more of theory based q on resonant freq formula instrumentation: only 22-3 q’s from instrumenta : input impedance of cro, q’s on why fet in electronic voltmeter, q’ on pitot tube analog, edc: q’s on tunnel diode,zener diode,q’s on class a,b,c amplifiers efficiency, duty cycle q’s on opamps: o/p voltage calculation of opamp, cascading lpf and hpf q’s on a/d,d/a converter, differentiator, integrator using opamp, their freq formuil
