A compact disk (CD) records audio signals digitally by using PCM. Assume that the audio signal bandwidth equals 15 kHz.

(a). If the Nyquist sample are uniformly quantized into L=65,536 levels and then binary-coded, determine the number of binary digits required to encode a sample.
(b). If the audio signal has average power of 0.1 W and peak voltage of 1 V. Find the resulting ratio of signal to quantization noise (SQNR) of the uniform quantizer output in part (a).
(c). Determine the number of binary digits per second (bit/s) required to encode the audio signal and minimum bandwidth required to transmit the encoded signal.
