(b) If the Nyquist samples are quantized into 65536 levels (L
binary-coded, what number of binary digits is required to encode a sample.
(c) Determine the number of binary digits/s (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 44100 samples/s. If L = 65536, determine
the number of pulses/s required to encode the signal.
