Compact disc(CD) records audio signals digitally by means of a binary code. Assume an audio signal bandwidth of 15 kHz. a. What is the Nyquist rate? b. If the Nyquist samples are quantized into 65,536 levels (L = 65,536) and then binary coded, what number of binary digits is required to encode a sample. c. Determine the number of binary digits per second (bits/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/s. If L = 65,536, determine the number of pulses per second required to encode the signal.
