1. Pulse Code Modulation: In a compact disk (CD) system, each stereo track is encoded using 16-bit PCM with two times oversampling of the analog signal (i.e., the sampling rate is twice the Nyquist rate). Suppose the analog signal bandwidth is 20 kHz. (a) What is the data rate of the left stereo track? What is the combined data rate of both tracks? (b) Find the peak SNR in decibels. (c) A data CD holds approximately 650 MB (= 650 x 220 x 8 bits) of information. How many minutes of music can be stored on a data CD, assuming both left and right tracks are recorded.
