Reconstruction filter — In a mixed signal system (analog and digital), a reconstruction filter (or anti imaging filter) is used to construct a smooth analogue signal from the output of a digital to analogue converter (DAC) or other sampled data output device.ampled data … Wikipedia
Filter bank — A filter bank is an array of band pass filters that separates the input signal into several components, each one carrying a single frequency subband of the original signal. It also is desirable to design the filter bank in such a way that… … Wikipedia
Spectral phase interferometry for direct electric-field reconstruction — In ultrafast optics, spectral phase interferometry for direct electric field reconstruction (SPIDER) is an ultrashort pulse measurement technique.The basicsSPIDER is an interferometric ultrashort pulse measurement technique in the frequency… … Wikipedia
Quadrature mirror filter — In digital signal processing, a quadrature mirror filter is a filter most commonly used to implement a filter bank that splits an input signal into two bands. The resulting high pass and low pass signals are often decimated by a factor of 2,… … Wikipedia
Mitchell-Netravali-Filter — Die Mitchell Netravali Filter oder BC Splines sind eine vorrangig in der Computergrafik verwendete Gruppe von Rekonstruktionsfiltern, die zum Beispiel beim Antialiasing oder bei der Skalierung von Rastergrafiken verwendet werden können. In… … Deutsch 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
Fast Kalman filter — The fast Kalman filter (FKF), devised by Antti Lange (1941 ), is an extension of the Helmert Wolf blockingfn|1 (HWB) method from geodesy to real time applications of Kalman filtering (KF) such as satellite imaging of the Earth. Kalman filters are … 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
Lifting scheme — The lifting scheme is a technique for both designing wavelets and performing the discrete wavelet transform.Actually it is worthwhile to merge these steps and design the wavelet filters while performing the wavelet transform.This is then called… … Wikipedia
Nyquist frequency — Not to be confused with Nyquist rate. Frequencies above ƒs/2 (the Nyquist frequency) have an alias below ƒs/2, whose value is given by this graph. ƒs/2 is also called folding frequency, because of the symmetry between 0 and ƒs. The Nyquist… … Wikipedia
Direct digital synthesizer — A DDS function generator. Direct Digital Synthesizer (DDS) is a type of frequency synthesizer used for creating arbitrary waveforms from a single, fixed frequency reference clock. Applications of DDS include: signal generation, local oscillators… … Wikipedia
