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obtained by decomposing a … See more The development of fast algorithms for DFT can be traced to Carl Friedrich Gauss's unpublished work in 1805 when he needed it to interpolate the orbit of asteroids Pallas and Juno from sample observations.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 … See more Cooley–Tukey algorithm By far the most commonly used FFT is the Cooley–Tukey algorithm. This is a divide-and-conquer algorithm See more Bounds on complexity and operation counts A fundamental question of longstanding theoretical interest is to prove lower bounds on the complexity and exact operation counts of fast Fourier transforms, and … 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 transforms an array … See more An $${\textstyle O(N^{5/2}\log N)}$$ generalization to spherical harmonics on the sphere S with N nodes was described by Mohlenkamp, … See more WebApr 9, 2024 · An essential precondition for the effective use of low-frequency spread-spectrum acoustic signals is their synchronous acquisition. Due to the low bit rate that low-frequency spread-spectrum signals have, the length of the spreading spectrum code and the number of intra-chip carriers need to be precisely designed to balance the acquisition …
