\end{aligned}}} Unlike the Eq.1 definition, the Fourier transform is no longer a unitary transformation, and there is less symmetry between the formulas

as the Mellin transform, and is closely related to the Fourier transform. Unlike the Fourier transform, the Laplace transform is often an analytic function

fast Fourier transform (FFT) is an algorithm that computes the discrete Fourier transform (DFT) of a sequence, or its inverse (IDFT). A Fourier transform

A Fourier series (/ˈfʊrieɪ, -iər/) is an expansion of a periodic function into a sum of trigonometric functions. The Fourier series is an example of a

operations. The decomposition process itself is called a Fourier transformation. Its output, the Fourier transform, is often given a more specific name, which

fractional Fourier transform (FRFT) is a family of linear transformations generalizing the Fourier transform. It can be thought of as the Fourier transform

computing, the quantum Fourier transform (QFT) is a linear transformation on quantum bits, and is the quantum analogue of the discrete Fourier transform. The

This is a list of linear transformations of functions related to Fourier analysis. Such transformations map a function to a set of coefficients of basis
