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...

Problem 3 Assume that a 3 KHz channel is to transmit some given binary data. What data rate will this channel support in bits/second for the following line codes: a. Binary polar signaling with full width rectangular pulses (NRZS). b. Binary polar signaling with raised cosine pulses with a=0.25. Here, use the exact/absolute raised cosine BW. 4-ary signaling with raised cosine pulses with a =0.25. Here too, use the exact/absolute raised cosine BW.

Consider the transmission of data via PAM over a channel that has a bandwidth of 1500 Hz. Using square root raised cosine filter at transmitter and receiver, show how the symbol rate varies as a function of the excess bandwidth. In particular, determine the symbol rate for excess bandwidths of 25%, 50%, 75%, and 100%.
