Sampling (signal processing) — Signal sampling representation. The continuous signal is represented with a green color whereas the discrete samples are in blue. In signal processing, sampling is the reduction of a continuous signal to a discrete signal. A common example is the … Wikipedia
FM broadcast band — The FM broadcast band, used for FM broadcast radio by radio stations, differs between different parts of the world. In Europe and Africa (ITU region 1), it spans from 87.5 to 108.0 megahertz (MHz), while in America (ITU region 2) it goes only… … Wikipedia

Nyquist rate — Not to be confused with Nyquist frequency. Spectrum of a bandlimited signal as a function of frequency In signal processing, the Nyquist rate, named after Harry Nyquist, is two times the bandwidth of a bandlimited signal or a bandlimited channel … Wikipedia
Anti-aliasing filter — An anti aliasing filter is a filter used before a signal sampler, to restrict the bandwidth of a signal to approximately satisfy the sampling theorem. Since the theorem states that unambiguous interpretation of the signal from its samples is… … Wikipedia
