PGECET ECE Test Papers

Hii guys , Can you please provide me Previous year Post Graduate Engineering Common Entrance Test paper ??? As I want to appear in this exam .

[Shaleen]

: As you said you want to appear Post Graduate Engineering Common Entrance Test , For take Admission in Post Graduate Engineering programme

Here I am providing previous year PGECET exam paper


In TDM non essential frequency components of the modulating signal are removed by

(A) sampler
(B) attenuator
(C) pre-alias filter
(D) modulator

Coherent demodulation of FSK signal can be affected using

(A) correlation receiver
(B) bandpass filter and envelope detectors
(C) discriminator detection
(D) above all

Epitaxial growth is used in integrated circuit

(A) because it produces low parasitic capacitance

(B) because it yields back-to-back isolating junctions

(C) to grow single crystal n -doped silicon on a single-crystal p -type substrate

(D) to grow selectively single-crystal p -doped silicon of one resistivity on p -type substrate of a different resistivity.

Assertion (A) In the self bias CE transistor amplifier a single battery is used.

Reason (R) The collector base junction is forward biased by VCC .

Chose the correct option:

(A) Both A and R individually true and R is the correct explanation of A.

(B) Both A and R individually true and but R is not the correct explanation of A.

(C) A is true but R is false

(D) A is false

In TDM non essential frequency components of the modulating signal are removed by

(A) sampler (B) attenuator

(C) pre-alias filter (C) modulator

Coherent demodulation of FSK signal can be affected using

(A) correlation receiver (B) bandpass filter and envelope detectors

(C) discriminator detection (C) above all

The dominant mode in a rectangular waveguide is TE10 because this mode has

(A) no attenuation (B) no cut-off

(C) no magnetic field component (D) the highest cut-off wavelength

Consider the following 8085 assembly program

DLT : XRA A

DSPLY : MOV A, B

MVI A, DATA1

MOV B, A

SUI 51H

JC DLT

MOV A, B

SUI 82H

JC DSPLY

OUT PORT1

HLT

OUT PORT2

HLT

This program will display

(A) the bytes from 51H to 82H at PORT2

(B) 00H AT PORT1

(C) all byte at PORT1

(D) the bytes from 52H to 81H at PORT 2

Consider the following program

MVI A, BYTE1

RRC

RRC

If BYTE1 =32H, the contents of A after the execution of program will be

(A) 08H (B) 8CH

(C) 12H (D) None of the above

The response of a system S to a complex input x t e j t ( ) =

(A) is definitely LTI (B) is definitely not LTI

(C) may be LTI (D) information is insufficient
