As you want I am here giving you sample paper for PGECET Computer Science and Engineering (CSE) Entrance Exam.

Sample paper :

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.


The chemical reaction involved in epitaxial growth in IC chips takes place at a temperature of about
(A) 500° C (B) 800° C
(C) 1200° C (D) 2000° C


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

(A) 10 bits (B) 13 bits
(C) 8 bits (D) 18 bits


In TDM non essential frequency components of the modulating signal are removed by
(A) sampler (B) attenuator
(C) pre-alias filter (C) modulator

Q18. Coherent demodulation of FSK signal can be affected using
(A) correlation receiver (B) bandpass filter and envelope detectors
(C) discriminator detection (C) above all

Two dissimilar antennas having their maximum directivities equal,
(A) must have their beamwidths also equal.
(B) can not have their beamwidths equal because they are dissimilar antenna.
(C) may not necessarily have their maximum power gain equal.
(D) must have their effective aperture areas ( capture areas) also equal.


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
