A compact disc (CD) records audio signals digitally by using PCM. Let the audio signal bandwidth be 15 kHz. a) If the Nyquist samples 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 (SNR = Psig/q,) of the uniform quantizer output in part (a). Give your answer in dB. %3D %3D
