"The FFT is used in digital recording, sampling, additive synthesis and pitch correction software. The FFT's importance derives from the fact that it has made working in the frequency domain equally computationally feasible as working in the temporal or spatial domain. Some of the important applications … See more 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 … See more Let $${\displaystyle x_{0}}$$, …, $${\displaystyle x_{N-1}}$$ be complex numbers. The DFT is defined by the formula $${\displaystyle X_{k}=\sum _{n=0}^{N-1}x_{n}e^{-i2\pi kn/N}\qquad k=0,\ldots ,N-1,}$$ See more In many applications, the input data for the DFT are purely real, in which case the outputs satisfy the symmetry $${\displaystyle X_{N-k}=X_{k}^{*}}$$ and efficient FFT … See more As defined in the multidimensional DFT article, the multidimensional DFT $${\displaystyle X_{\mathbf {k} }=\sum _{\mathbf {n} =0}^{\mathbf {N} -1}e^{-2\pi i\mathbf {k} \cdot (\mathbf {n} /\mathbf {N} )}x_{\mathbf {n} }}$$ transforms an array … See more The development of fast algorithms for DFT can be traced to Carl Friedrich Gauss's unpublished work in 1805 when he needed it to interpolate the orbit of asteroids Pallas and Juno from sample observations. His method was very similar to the one … See more Cooley–Tukey algorithm By far the most commonly used FFT is the Cooley–Tukey algorithm. This is a divide-and-conquer algorithm that recursively breaks down a DFT of any composite size $${\textstyle N=N_{1}N_{2}}$$ into many smaller DFTs of sizes See more Bounds on complexity and operation counts A fundamental question of longstanding theoretical interest is to prove lower bounds on the See more " - Fft formanowitz
