An analog signal with a bandwidth of 4.2 MHz is to be converted into binary PCM and transmit- ted over a channel. The peak-signal quantizing noise ratio at the receiver output must be at least 55 dB. (a) If we assume that P=0 and that there is no ISI, what will be the word length and the number of quantizing steps needed? (b) What will be the equivalent bit rate? (c) What will be the channel null bandwidth required if rectangular pulse shapes are used?
