Webby Marco Taboga, PhD. The Discrete Fourier Transform (DFT) is used to analyze the frequencies of a signal. But what are these frequencies exactly? Sometimes, the terminology can get a little bit confusing. To check how the terms are used, we analyzed more than 50 different sources (books and lecture notes). WebFor a sample set of 1024 values, the FFT is 102.4 times faster than the discrete Fourier transform (DFT). The basis for this remarkable speed advantage is the `bit-reversal' scheme of the Cooley-Tukey algorithm. Eliminating the burden of `degeneracy' by this means is readily understood using vector graphics.
