Question 5: An analog signal is PCM formatted and transmitted using binary waveforms over a channel that is bandlimited to 100 kHz. Assume that 32 quantization levels are used and that the overall equivalent transfer function is of the raised cosine type with roll- off r = 0.6. (a) Find the maximum bit rate that can be used by this system without introducing ISI. (b) Find the maximum bandwidth of the original analog signal that can be accommo- dated with these parameters. (c) Repeat parts (a) and (b) for transmission with 8-ary PAM waveforms.
