ALL meanings of fourier transform
Fou·rier trans·form
F f - noun Technical meaning of fourier transform (mathematics) A technique for expressing a waveform as a weighted sum of sines and cosines. Computers generally rely on the version known as discrete Fourier transform. Named after J. B. Joseph Fourier (1768 -- 1830). See also wavelet, discrete cosine transform. (1997-03-9) 1
- noun fourier transform a mapping of a function, as a signal, that is defined in one domain, as space or time, into another domain, as wavelength or frequency, where the function is represented in terms of sines and cosines. 1
- noun fourier transform (analysis) a transform, applied to a function, used to determine the function's frequency composition (temporal, spatial or otherwise); it has many scientific and industrial applications, especially in signal processing. 0
- noun fourier transform an integral transform, used in many branches of science, of the form F(x) = [1/√(2π)]∫eixyf(y)dy, where the limits of integration are from –∞ to +∞ and the function F is the transform of the function f 0
