Electronics and communication exam Last years paper

Can you provide me the GATE Electronics and communication exam Last years paper????

[Arun Vats]

Here I am sharing the GATE Electronics and communication exam Last years paper:

A source alphabet consists of N symbols with the probability of the first two symbols being the
same. A source encoder increases the probability of the first symbol by a small amount  and
decreases that of the second by  . After encoding, the entropy of the source
(A) increases (B) remains the same
(C) increases only if N = 2 (D) decreases


With 10 V dc connected at port A, the current drawn by 7 connected at port B is
(A) 3/7 A (B) 5/7 A (C) 1 A (D) 9/7 A

For the same network, with 6 V dc connected at port A, 1connected at port B draws 7/3 A.
If 8 V dc is connected to port A, the open circuit voltage at port B is
(A) 6 V (B) 7 V (C) 8 V (D) 9 V
