What is the Nyquist sampling theorem?

The Nyquist Theorem, also known as the sampling theorem, is a principle that engineers follow in the digitization of analog signals. For analog-to-digital conversion (ADC) to result in a faithful reproduction of the signal, slices, called samples, of the analog waveform must be taken frequently. read more

In the field of digital signal processing, the sampling theorem is a fundamental bridge between continuous-time signals (often called "analog signals") and discrete-time signals (often called "digital signals"). read more

The sampling theorem is not by Nyquist. It was derived by Shannon. Nyquist’s theorem deals with the maximum signalling rate over a channel of given bandwidth. Since the results are similar, people often associate Nyquist’s name with the sampling theorem. read more
