Difference Between FFT and DFT

WebThe basis functions of DFT are "discretized sine waves" whereas the basis functions of DWT, the socalled wavelets, have very peculiar graphs. But the exact shape of these wavelets plays no rôle in the applications: It is the algebraic structure of the whole setup that is essential. Share. WebDFT is a discrete version of FT whereas FFT is a faster version of the DFT algorithm.DFT established a relationship between the time domain and frequency domain representation whereas FFT is an implementation of DFT. computing complexity of DFT is O (M^2) whereas FFT has M (log M) where M is a data size Share Cite Follow baitul hikmah depok
