A compact disc (CD) records audio signals digitally by using Pulse Code Modulation (PCM). Assume the audio signal bandwidth to be f, kHz (as in table Q4) and if the Nyquist samples are quantized into L = (as in table Q4) levels. Determine the following: %3! i. Nyquist rate. ii. Number of binary digits required to encode each sample. iii. Number of binary digits per second (bits/s) required to encode the audio signal. iv. Minimum channel band width required to transmit this PCM signal. v. Sampling frequency if the audio signal is sampled at a rate of 10.0% lower than the minimum Nyquist's sampling frequency. Evaluate whether the Nyquist criterion satisfied. If the sampling rate does not fulfill the Nyquist criterion, explain what will happen to the transmitted signal.
