2.16. In the compact disc (CD) digital audio system, an analog signal is digitized so that the ratio of the peak-signal power to the peak-quantization noise power is at least 96 dB. The sampling rate is 44.1 kilosamples/s. (a) How many quantization levels of the analog signal are needed for (S/N,)penk = 96 JB? (b) How many bits per sample are needed for the number of levels found in part (a)? (e) What is the data rate in bits/s?
