Explanation of 44.1 kHz CD sampling rate

The CD sampling rate has to be larger than about 40 kHz to fulfill the Nyquist criterion that requires sampling at twice the maximum analog frequency, which is about 20 kHz for audio. The sampling frequency is chosen somewhat higher than the Nyquist rate since practical filters neede to prevent aliasing have a finite…
