9-2) similar to Lathi & Ding, Prob. P.5.2-1 A compact disc (CD) records audio signals digitally by using PCM. Assume that the audio signal bandwidth equals 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 a peak voltage of ±1V and an average signal power of 0.1 V2, find the resulting ratio of signal to quantization noise (SQNR) for the system. (c) Determine the number of binary digits per second (bit/s) required to encode the audio signal. (d) For practical reasons discussed in the text, signals are sampled at a rate well above the Nyquist rate. Practical CDs use 44,100 samples per second. If L = 65,536, determine the number of bits per second required to encode the signal and the minimum bandwidth required to transmit the encoded signal.
