Bravo to Harry Nyquist and Claude Shannon! In the 1920s, these gentlemen created the now-well-known Nyquist theorem, which states that when sampling a signal at discrete intervals, the sampling must ...

The minimum sampling rate of 2W samples per second for a signal having maximum frequency of W is called the Nyquist Rate. What is the Nyquist Rate? In data communication, the sampling theorem states ...

The concept behind digitizing sound. Working at Bell Labs, Harry Nyquist discovered that it was not necessary to capture the entire analog waveform, and samples of the wave could be taken at various ...

A look at the Nyquist sampling theorem. How to deal with aliasing by attenuating signals using low-pass filters (i.e., an antialiasing filter, or AAF). AAF requirements for different ADCs. A deep dive ...

Sampling protocols have drastically changed with the discovery of compressive sensing (CS) data acquisition and signal recovery 1,2. Prior to the development of CS theory, the Shannon-Nyquist theorem ...
