A compact disk (CD) recording system samples each of two stereo signals with a 16-bit analog-to-digital converter (ADC) at 44.1 kb/s.
a) Determine the output signal-to-quantizing ratio for a full-scale sinusoid.
b) The bit stream of digitized data is augmented by the addition of error-correcting bits, clock extraction bits, and display and control bit fields. These additional bits represent 100 percent overhead. Determine the output bit rate of the CD recording system.
c) The CD can record an hour's worth of music. Determine the number of bits recorded on a CD.
d) For a comparison, a high-grade collegiate dictionary may contain 1500 pages, 2 columns per page, 100 lines per columns, 8 words per line, 6 letters per word, and 7 b per letter on average. Determine the number of bits required to describe the dictionary, and estimate the number of comparable books.
