Question
Q4] A compact disc (CD) records audio signals digitally by using PCM. Assume the audio signal
bandwidth to be 15 kHz.
(a) What is the Nyquist rate?
(b) If the Nyquist samples are quantized into q = 65,536 levels and then binary coded, determine the
number of binary digits required to encode a sample.
(c) Determine the number of binary digits per second (bit/s) required to encode the audio signal.
(d) If, for practical reasons, the signals are sampled at a rate well above the Nyquist rate. Practical
CDs use 44,100 samples per second. If q - 65,536, determine the number of bits per second
required to encode the signal, and the minimum bandwidth required to transmit the encoded signal.
