question

An analog signal is quantized and encoded using pulse code modulation (PCM). (a) If the number of quantization levels M = 16 and the word length is 400 \musec determine the minimum channel bandwith (f_c) required to transmit the bi-nary PCM signal. (b) If the channel has a bandwidth half of what is found in (a), determine the new number of quantiza-tion levels so that the PCM signal can pass through this channel.
