This picture shows the input signal as the DFT sees it. This is a SignalProcessing DFT compute forward discrete Fourier transform InverseDFT compute inverse discrete Fourier transform Calling Sequence Parameters Problem 18.4. 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.

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.
