Web2The term “coefficient” is commonly applied to DFT values. This is appropriate because XŒk is the (complex amplitude) coeffi-cient of ej.2=N/kn in the IDFT (67.5). 3The … WebThe discrete Fourier transform (DFT) can be seen as the sampled version (in frequency-domain) of the DTFT output. It's used to calculate the frequency spectrum of a discrete-time signal with a computer, because computers can only handle a finite number of values. I would argue against the DFT output being finite.
