(7) An analog signal with a bandwidth of 4.2kHz is to be converted into binary PCM and transmitted over a channel. The peak signal to quantization ratio at the receiver output must be at least 55dB. (a) If we assume that Pp 0 and that %3D there is no ISI, what will be the word length and the number of quantization steps needed? (b) What will be the equivalent bit rate? (c) What will be the channel bandwidth required if rectangular pulse shapes are used?
