How many songs can be recorded digitally on a 600 MB CD if each song is recorded in quad sound, plays an average of 3 minutes at a maximum reproducible frequency of 2 kHz and the number of recognizable sound levels is about 16 million?
V = H * t * i N = 2 ^ i t = 180 sec
H = 2kHz
i = 24 bits = 3 bytes
V = 2 * 1000 * 180 * 3 * 4 = 4,320,000 bytes = 4,218.75 KB = 4.12 MB
600 MB: 4.12 MB = 145.6
Answer: 145 songs.
