But his original contribution was not the sampling theorem. Inspired by the work of Fourier, Nyquist discovered that there is a maximum rate at which signals could be sent through a bandlimited channel. For a bandwidth of B, 2B signals per second is the limit (the capacity). This, of course, does not set the limit on how much information you can squeeze into a single symbol/signal, but it shows something remarkable - the bandwidth of the channel limits the signaling rate of a channel. 20 years later, and inspired by Nyquist, Claude Shannon would publish his Mathematical Theory of Communication [2], which combined Nyquist's signalling rate capacity in a bandlimited channel with the impact of noise.
