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… WebAug 28, 2013 · The FFT is a fast, O [ N log N] algorithm to compute the Discrete Fourier Transform (DFT), which naively is an O [ N 2] computation. The DFT, like the more familiar continuous version of the Fourier transform, has a forward and inverse form which are defined as follows: Forward Discrete Fourier Transform (DFT): X k = ∑ n = 0 N − 1 x n ⋅ e ...

WebNov 24, 2024 · 1 Answer. No. An FFT will propagate any unknown input to every output. This because in a transform such as a DFT, every output value directly depends on every input value, and thus can not be computed without known values for every input. Or, an alternate answer is Yes: If any input to an FFT is an NaN, just output the FFT result as an ...
