It is important to distinguish between the concepts of the discrete-time Fourier transform (DTFT) and the discrete Fourier transform (DFT). The DTFT is a transform-pair relationship between a DT signal and its continuous-frequency transform that is used extensively in the analysis and design of DT systems.

WebThe Discrete Fourier Transform (DFT) Given a signal , its DFT is defined by 6.3. where or, as it is most often written, We may also refer to as the spectrum of , and is the th sample of the spectrum at frequency . Thus, the th sample of the spectrum of is defined as the inner product of with the th DFT sinusoid .
