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