Sketch the following spectra and tell which ones satisfy Nyquist€™s pulse-shape criterion. For those that do, find the appropriate sample interval, T, in terms of W. Find the corresponding pulse-shape function p(t). (Recall that II(f/A) is a unit-high rectangular pulse from - A/2 to A/2, Λ (f/B) is a unit-high triangle from -B to B.)
