Unformatted text preview: c) Does the pulse in b) have a wider or a narrower bandwidth than the pulse in a)? Solution. a) Use Ã« for t. A function p( ) defines its value in terms of what is in the parentheses. b) The function p(3t) falls to zero when 3t = Â±1, t = Â±1/3 c) The pulse in b) is 1/3 as wide, and requires 3 times the bandwidth. Problem 3 The theoretical channel capacity C relating to bandwidth H, signal power S, and noise power density N /2 is Suppose that at H = 2 megaherz the capacity is 4 megabits/second. If the bandwidth is doubled with no change in S and N , what is the new capacity? Aid for calculating base 2: Solution....
