Re: GATE ECE Solved question papers
As per your request here I am sharing the GATE Electronics & Communication engineering previous year question paper: In a base band communications link, frequencies upto 3500 Hz are used for signaling. Using a raised cosine pulse with 75% excess bandwidth and for no intersymbol interference, the maximum possible signaling rate in symbols per second is (A) 1750 (B) 2625 (C) 4000 (D) 5250 The output Y of a 2bit comparator is logic 1 whenever the 2bit input A is greater than the 2bit input B. The number of combinations for which the output is logic 1, is (A) 4 (B) 6 (C) 8 (D) 10 A source alphabet consists of N symbols with the probability of the first two symbols being the same. A source encoder increase the probability of the first symbol by a small amount ε and decreases that of the second by ε. After encoding, the entropy of the source (A) increases (B) remains the same (C) increases only if N = 2 (D) decreases Complete question paper is in the attachment, please click on it ..
