Choose a set of … 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 The DFT is obtained by … See more The development of fast algorithms for DFT can be traced to Carl Friedrich Gauss's unpublished work in 1805 when he needed it to interpolate the orbit of asteroids Pallas and Juno from sample observations.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 … 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 Let $${\displaystyle x_{0}}$$, …, $${\displaystyle x_{N-1}}$$ be complex numbers. The DFT is defined by the formula where 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 … See more Bounds on complexity and operation counts A fundamental question of longstanding theoretical interest … 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, along with an algorithm conjectured (but not proven) to have $${\textstyle O(N^{2}\log ^{2}(N))}$$ complexity; … See more

Webpolar and spherical Fourier transform respectively. It should be noted though that in the literature, the former often refers to the normal Fourier transform with wave vectors k expressed in polar coordinates (k,ϕk) [16] and the latter often refers to the SH transform [17]. Due to the extreme importance of the Laplacian in physics, the expansion WebFourier analysis on the sphere has practical relevance in tomography, geophysics, seismology, meteorology and crystallography. In analogy to the complex exponentials \(\mathrm{e}^{\mathrm{i} k x}\) on the torus, the spherical harmonics form the orthogonal Fourier basis with respect to the usual inner product on the sphere. johnson controls fire protection anchorage
