Last year papers of IES ( Indain Engineering Services) Electronics and Telecommunication Engineering Examinations

IES-2012 Electronics & Telecommunication
Paper -1 (Objective)
Paper -2 (Objective)

This paper is as follows:
01. The threshold effect in demodulators is
(a) The rapid fall of output SNR when the input SNR falls below a particular value
(b) Exhibited by all the demodulators when the input SNR is low
(c) Exhibited by all AM suppressed carrier coherent demodulators
(d) Exhibited by correlation receivers
Ans : (a)

02. An amplitude modulated signal is
[ A + 0.5 A cos m t] cos ct where m and c are respectively, modulating and carrier
frequencies. The power efficiency is
(a) 11.11% (b) 0.25% (c) 4.32% (d) 50%
Ans : (a)

03. The signal x(t) = sin(200 t)+2 sin(400t) is modulated to produce a signal
g(t) = x(t) sin (400 t).
This is passed through a low pass filter having a cut-off frequency of 400Hz and pass
band gain of 2. Then the output signal after the filter is
(a) 0 (b) 0.5 sin (200t) (c) sin(200t) (d) 2 sin(200t)
Ans : (b)

04. In communication systems, noise due to quantization error is
(a) Linear and signal dependent
(b) Non-linear and signal dependent
(c) Linear and signal independent at low frequencies only
(d) non-linear and signal dependent at low frequencies only
Ans : (a)

05. Match List I with List II and select the correct answer using the code given below the

Here I am providing you the attachment PDF file. You can download free from here.
