The discrete Fourier transform, or DFT, is the primary tool of digital signal processing. The foundation of the product is the fast Fourier transform (FFT), a method for computing the DFT with reduced execution time. Many of the toolbox functions (including Z -domain frequency response, spectrum and cepstrum analysis, and some filter design and Demand Flow Technology (DFT) is a strategy for defining and deploying business processes in a flow, driven in response to customer demand.DFT is based on a set of applied mathematical tools that are used to connect processes in a flow and link it to daily changes in demand. In mathematics, the discrete-time Fourier transform (DTFT) is a form of Fourier analysis that is applicable to a sequence of values. The DTFT is often used to analyze samples of a continuous function. The term discrete-time refers to the fact that the transform operates on discrete data, often samples whose interval has units of time. 0.25 0.125 − j0.3018 0  the correlation sequence, the Real DFT, correlation by convolution, matched and the Discrete Fourier Transform (DFT) (including Discrete Fourier Series,  Stäng.

The Discrete-time Fourier Transform provides the frequency domain (ω) representation for absolutely summable signals. This transformation is only defined for infinite length signals that are functions of a continuous variable of frequency.

In computing the DFT of real sequences it is possible to reduce the amount of computation by utilizing the fact that the sequence is real. In particular,   The graph of arg X(f) against frequency is known as the phase spectrum.
