(We could perform the algebraic acrobatics to convert Eq. (8) into a familiar sin (x)/x form, but we need not do that here.) With the original DFT input being exactly integer k cycles of a cosine sequence, to verify Eq. So let us call that sequence vŒn 2The 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 terminology “N-point DFT” means that the sequence xŒn is known for N time indices, and the DFT is computed at N frequencies in (67.2).

The purpose of performing a DFT operation is so that we get a discrete-time signal to perform other processing like filtering and spectral analysis on it. However, the process of calculating DFT is quite complex. DFT - Demand Flow Technology based manufacturing system.
