Difference Between FFT and DFT
WebThe two quantum chemistry methods widely used to calculate the properties are DFT and wave function theory (WFT). In WFT, one works explicitly with the wave function, which depends on 3n coordinates for an n-electron system with fixed nuclear coordinates. In contrast, the basic premise of DFT is that, for a given set of nuclear coordinates, the ... WebThe DFT differs from the discrete-time Fourier transform (DTFT) in that its input and output sequences are both finite; it is therefore said to be the Fourier analysis of finite-domain (or periodic) discrete-time functions. Is it the only difference? Edit: This article nicely explains the difference discrete-signals fourier-transform Share milgard bifold windows
