fourier transform

listen to the pronunciation of fourier transform
English - English
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
In mathematical analysis, an integral transform useful in solving certain types of partial differential equations. A function's Fourier transform is derived by integrating the product of the function and a kernel function (an exponential function raised to a negative complex power) over the interval from - to +. The Fourier transform of a function g is given by

discrete Fourier transform
The process of converting a discrete time-based function into its frequency-based representation
fast Fourier transform
An instance of performing one of these algorithms
fast Fourier transform
A member of a certain family of algorithms for efficiently computing the discrete Fourier transform of data
inverse Fourier transform
A mathematical operation that transforms a function for a discrete or continuous spectrum into a function for the amplitude with the given spectrum; an inverse transform of the Fourier transform
