  • Bandlimited — A bandlimited signal is a deterministic or stochastic signal whose Fourier transform or power spectral density is zero above a certain finite frequency. In other words, if the Fourier transform or power spectral density has finite support then… …   Wikipedia

  • bandlimited — adjective Describing a signal whose spectral power is zero outside of a band of frequencies …   Wiktionary

  • 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

  • Overshoot (signal) — An illustration of overshoot, followed by ringing and settle time. In signal processing, control theory, electronics, and mathematics, overshoot is when a signal or function exceeds its target. It arises especially in the step response of… …   Wikipedia

  • Nyquist–Shannon sampling theorem — Fig.1: Hypothetical spectrum of a bandlimited signal as a function of frequency The Nyquist–Shannon sampling theorem, after Harry Nyquist and Claude Shannon, is a fundamental result in the field of information theory, in particular… …   Wikipedia

  • Whittaker–Shannon interpolation formula — The Whittaker–Shannon interpolation formula or sinc interpolation is a method to reconstruct a continuous time bandlimited signal from a set of equally spaced samples. Contents 1 Definition 2 Validity condition 3 Interpolation as convolution sum …   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

  • Analog-to-digital converter — An analog to digital converter (abbreviated ADC, A/D or A to D) is an electronic integrated circuit, which converts continuous signals to discrete digital numbers. The reverse operation is performed by a digital to analog converter… …   Wikipedia

  • Zero-order hold — The zero order hold (ZOH) is a mathematical model of the practical signal reconstruction done by a conventional digital to analog converter (DAC). That is, it describes the effect of converting a discrete time signal to a continuous time signal… …   Wikipedia

  • Aliasing — This article applies to signal processing, including computer graphics. For uses in computer programming, please refer to aliasing (computing). In statistics, signal processing, computer graphics and related disciplines, aliasing refers to an… …   Wikipedia

  • Intersymbol interference — In telecommunication, intersymbol interference (ISI) is a form of distortion of a signal in which one symbol interferes with subsequent symbols. This is an unwanted phenomenon as the previous symbols have similar effect as noise, thus making the… …   Wikipedia
