17. A compact disc (CD) records audio signal 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 L = 65536 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) For practical reasons, signals are sampled at a rate well above the Nyquist rate Practical CDs use 44 100
