Twenty signals each of 5 kHz bandwidth are sampled and multiplexed at a rate of

20,000 samples/s. Each sample is then coded into six binary digits. Find the PCM output rate and the channel bandwidth. What will be the output bit rate if instead of binary pulses four-level pulses are transmitted?

Suppose a full-scale voice signal with bandwidth 10 kHz is sampled at the Nyquist rate and quantized by using a b-bit uniform quantizer. The bit stream is then transmitted using binary PAM over an AWGN channel that is capable of passing frequencies in the range of [0, 200kHz]. 1. Suppose that the signal is transmitted at the maximum bit rate and the two-sided spectral density of noise at the receiver is 10-6 W/Hz. What is the required signal power to...

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.
