Question

A signal in the frequency range 300 to 3300 Hz is limited to a peak-to-peak swing of 10v. It is sampled at 8000 sample/s and the samples are quantized to 64 evenly spaced levels. Calculate and compare the bandwidths and ratio of peak signal power to quantization noise if the quantized samples are transmitted either as binary pulse or as four-level pulses. Assume that the system bandwidth is defined by the main spectral lobe of the signal.
