A fast Fourier transform (FFT) is an algorithm that computes the discrete Fourier transform (DFT) of a sequence, or its inverse (IDFT). Fourier analysis converts a signal from its original domain (often time or space) to a representation in the frequency domain and vice versa. The DFT is obtained by decomposing a sequence of values into components of different frequencies. This operation is useful in many fields, but computing it directly from the definition is often too slow to be practical… WebFiltering a signal using FFT Filtering is a process in signal processing to remove some unwanted part of the signal within certain frequency range. There are low-pass filter, which tries to remove all the signal above certain cut-off frequency, and high-pass filter, which does the opposite.
