Oversampling — In der digitalen Signalverarbeitung spricht man von Überabtastung oder engl. Oversampling [oʊvɚˈsæmplɪŋ], wenn ein Signal mit einer höheren Abtastrate bearbeitet wird, als für die Darstellung der Signalbandbreite benötigt wird. Eine Überabtastung … Deutsch Wikipedia
Oversampling — In signal processing, oversampling is the process of sampling a signal with a sampling frequency significantly higher than twice the bandwidth or highest frequency of the signal being sampled. Oversampling helps avoid aliasing, improves… … 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
Delta-sigma modulation — Delta sigma (ΔΣ; or sigma delta, ΣΔ) modulation is a method for encoding high resolution or analog signals into lower resolution digital signals. The conversion is done using error feedback, where the difference between the two signals is… … Wikipedia

Representations of these signals can be recorded using either digital or analog techniques. An analog… … Wikipedia
Analog sound vs. digital sound — Analog sound versus digital sound compares the two ways in which sound is recorded and stored. Actual sound waves consist of continuous variations in air pressure. Representations of these signals can be recorded in either digital or analog… … Wikipedia
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
