Problem 2: An analog signal is to be converted into a PCM signal that is a binary polar NRZ line code. The signal is transmitted over a channel that is absolutely bandlimited to B-8 kHz. Assume that the PCM quantizer has 32 steps and that the overall equivalent system transfer function He is of the raised cosine-rolloff type with r 0.5. Find the maximum symbol rate D that can be supported over this channel without causing ISI a) c) Find...

(b) x(t) = cos(12000nt). (c) x(t) = cos(18000nt).
