Nyquist’s Theorem

By Cari Jansen | November 3, 2006

Amazingly this law of sound dates back to 1928:
"for a digital system to reproduce the entire frequency range of human hearing—20 to 20,000 Hz—then the system has to sample the incoming signal at two times the highest input frequency, or 40 kHz. This doubled figure is known as the sampling rate or sampling frequency"

Web Reference: 1928 Harry Nyquist Nyquist Theorem (2006, Prism Business Media Inc.)
