Derivation of the Maxwell-Boltzmann distribution function

The discrete Fourier transform transforms a sequence of N complex numbers into another sequence of complex numbers, which is defined by The transform is sometimes denoted by the symbol , as in or or . The DFT has many applications, including purely mathematical ones with no physical interpretation. But physically it can be related to signal processing as a discrete version (i.e. sam… 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.
