In this problem, we evaluate the equalization needed for the aperture effect in a PAM system. The operating frequency A? = A?s/2, which corresponds to the highest frequency component of the message signal for a sampling rate equal to the Nyquist rate. Plot 1/sinc (0.5T/T,) versus T/Ts, and hence find the equalization needed when T/Ts = 0.1.
