A compact disc (CD) recording system samples each of two
stereo signals with a 16-bit ADC at 44.1 kilosamples/s.

a. Determine the average output signal-toquantization noise
ratio for PAPR = 1.

b. If the recorded music is designed to have a PAPR = 20,
determine the average output signal-to-quantization noise ratio.

c. The bit stream at the ADC output is augmented by
error-correcting bits, bits for clock extraction and display and control. These
additional bits represent 100% overhead, the bit rate at ADC output is doubled.
Determine the output bit rate of this CD recorder system.

Determine the output bit rate of this CD recorder system.

d. If the CD can record 75 minutes of music, determine the
number of bits recorded on a CD.

e. Consider a book of 1500 pages, 100 lines/ page, 15
words/line, 6 letters/word, and 6 bits/letter. Determine the number of bits
required to store the book and estimate the number of comparable books that can
be stored on a CD.
