I am going to getting exam of ECE so please provide me solved question paper of ECE for my preparation.

You are searching for question paper so we are providing you ECE Gate paper.

Here is solved question paper of ECE for your preparation from given pdf file:-


A transmission line of characteristic impedance 50Ω is terminated by a 50Ω load.
When excited by a sinusoidal voltage source at 10GHz, the phase difference π between two points spaced 2mm apart on the line is found to be 4 radians. The phase velocity of the wave along the line is
(A) 80.8 10 m / s ×
(B) 81.2 ×10 m / s
(C) 81.6 10 m / s ×
(D) 83 10 m / s ×

Answer: -(C)
Exp: -
0Z 50 = W; LZ =50 Ω For 4 π radians the distance is 2mm the phase velocity
10 7 8 P 3 2 10 v 16 10 1.6 10 m / s 2 16 10 − − ω ×p× = = = × = ×pβ ×

3. An analog signal is band-limited to 4kHz, sampled at the Nyquist rate and the samples are quantized into 4 levels. The quantized levels are assumed to be independent and equally probable. If we transmit two quantized samples per second, the information rate is ________ bits / second.
(A) 1
(B) 2
(C) 3
(D) 4

Answer: -(D)
Exp: -Since two samples are transmitted and each sample has 2 bits of information, then the information rate is 4 bits/sec.


Here I am attaching a file to get full solved question paper of ECE for your preparation you can download this attachment it is free to download.
