Can you give me question paper for GATE Electronics And Communication Engineering examination ??

here I am giving you question paper for GATE Electronics And Communication Engineering examination in PDF file with it so you can get it easily..

Q.15 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

Q.28 A transmission line with a characteristic impedance of 100 is used to match a 50 section to a
200 section. If the matching is to be done both at 429 MHz and 1 GHz, the length of the
transmission line can be approximately
