In mathematics, the discrete Fourier transform DFT converts a finite sequence of equally-spaced samples of a function into an equivalent-length sequence of equally-spaced samples of the discrete-time Fourier transform DTFTwhich is a complex-valued function of frequency.

Ze transformeert een periodieke periode N en discrete n getallen rij opnieuw in een periodieke discrete rij.

Discrete Fourier transform yago-res: De rij van N complexe getallen x 0If the original dtskretna spans all the non-zero values of a function, its DTFT is continuous and periodicand the DFT provides discrete samples of one cycle. Een normalisatiefactor van voor zowel DFT als IDFT maakt de transformaties unitair, hetgeen enkele theoretische voordelen biedt, maar vaak is het praktischer om de schaling van bovenstaande definities aan te houden.

Prior to its current usage, the “FFT” initialism may have also fourriera used for the ambiguous term “finite Fourier transform”.

Kwantowa transformata Fouriera

Diversamente dalla trasformata continua di Fourier, pertanto, la DFT richiede in ingresso una funzione discreta i cui valori sono in generale complessi e non nulli, ed hanno una transformatq limitata. De transformatie wordt ook wel genoteerd alszoals in. Transfromata Fourier transform dbpedia-ko: The interval at which the DTFT is sampled is the reciprocal of the duration of the input sequence. Activityfrom Named Graph: Si tratta di una trasformata che converte una collezione finita di campioni equispaziati di una funzione in una collezione di coefficienti di una combinazione lineare di sinusoidi complesse, ordinate al crescere della dyskretha.

Discrete Fourier transform dbpedia-el: Discrete Fourier transform dbpedia-de: Discrete Fourier transform dbpedia-ja: De discrete fouriertransformatie aangeduid als is een lineaire transformatie en een discrete vorm van de fouriertransformatie.

Formalmente, hay una diferencia clara: The DFT is the most important discrete transform, used to perform Fourier analysis in many practical applications. The DFT is also used to efficiently solve partial differential equations, and to perform other operations such as convolutions or multiplying large integers.

About: Discrete Fourier transform

It has the same sample-values as the original input sequence. Discrete Fourier transform freebase: Discrete Fourier transform dbpedia-fr: Since it deals with a finite amount of data, it can be implemented in computers by numerical algorithms or even dedicated hardware.

Il est important de comprendre que la TFD ne calcule pas le spectre continu d’un signal continu. Discrete Fourier transform dbpedia-wikidata: Questo rende la DFT ideale per l’elaborazione di informazioni su un elaboratore elettronico. Discrete Fourier transform prov: Discrete Fourier transform dbpedia-es: Discrete Fourier transform dbpedia-pl: In digital signal processing, the function is any quantity or signal that varies over time, such as the pressure of a sound wave, a radio signal, or daily temperature readings, sampled over a finite time interval often defined by a window function.


The DFT is therefore said to transtormata a frequency domain representation of the original input sequence. In image processing, the samples can be the values of pixels along a row or column of a raster image. Discrete Fourier transform An Entity of Type: Discrete Fourier transform dbpedia-nl: Ze is erg analoog aan de discrete fourierreeks; in de transformatie is het transformeren belangrijk, terwijl bij de reeks het accent ligt op het kunnen schrijven als som van complexe e-machten.

Discrete Fourier transform dbpedia-id: Discrete Fourier transform dbpedia-it: Sie bildet ein zeitdiskretes endliches Signal, welches periodisch fortgesetzt wird, auf ein diskretes, periodisches Frequenzspektrum ab, das auch als Bildbereich bezeichnet wird. Si tratta anche di un caso particolare della trasformata zeta.
