Analytic signal — Not to be confused with Analytic function. In mathematics and signal processing, the analytic representation of a real valued function or signal facilitates many mathematical manipulations of the signal. The basic idea is that the negative… … Wikipedia
Analytic function — This article is about both real and complex analytic functions. The article holomorphic function is solely about analytic functions in complex analysis. An analytic signal is a signal with no negative frequency components. In mathematics, an… … 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
Analytisches Signal — Ein analytisches Signal ist in der Signaltheorie ein komplexwertiges Zeitsignal, dessen Imaginärteil die Hilbert Transformierte des Realteils ist. Die Bezeichnung analytisch drückt aus, dass die Funktion im Komplexen differenzierbar ist (siehe… … Deutsch Wikipedia
Hilbert transform — In mathematics and in signal processing, the Hilbert transform is a linear operator which takes a function, u ( t ), and produces a function, H ( u )( t ), with the same domain. The Hilbert transform is named after David Hilbert, who first… … Wikipedia
Quadrature filter — In signal processing, a quadrature filter q(t) is the analytic representation of the impulse response f(t) of a real valued filter::q(t) = f {a}(t) = left(delta(t) + {i over pi t} ight) * f(t)If the quadrature filter q(t) is applied to a signal… … Wikipedia
Single-sideband modulation — (SSB) is a refinement of amplitude modulation that more efficiently uses electrical power and bandwidth. It is closely related to vestigial sideband modulation (VSB) (see below).Amplitude modulation produces a modulated output signal that has… … Wikipedia
Hilbert-Transformation — Die Hilbert Transformation ist in der Funktionalanalysis, einem Teilgebiet der Mathematik, eine lineare Integraltransformation. Sie ist nach David Hilbert benannt, welcher sie Anfang des 20. Jahrhunderts bei Arbeiten am Riemann–Hilbert Problem… … Deutsch Wikipedia
Instantaneous phase — In signal processing, the instantaneous phase (or local phase or simply phase ) of a complex valued function x(t), is the real valued function::phi(t) = arg(x(t))., (see arg function)And for a real valued signal s(t), it is determined from the… … Wikipedia
Envelope detector — An envelope detector is an electronic circuit that takes a high frequency signal as input, and provides an output which is the envelope of the original signal. The capacitor in the circuit stores up charge on the rising edge, and releases it… … Wikipedia
