Consider the following controlled ISI communication system: 1, n = 0 p(nT): = { q, n = -1, +1 0, otherwise Write down the modified Nyquist condition for the case of q = 0.5 in its simplest form. Assuming that we transmit the sequence a = [1101100010111] using p(t), determine the sample values of the received signal y(t) for q = 0.4.
