(signal processing) A generalized Fourier transform that performs an orthogonal, symmetric, involutive, linear operation on 2ᵐ real numbers (or complex numbers, although the Hadamard matrices themselves are purely real).

(signal processing) A special case of the short-time Fourier transform, used to determine the sinusoidal frequency and phase content of local sections of a signal as it changes over time.

(mathematical analysis, number theory, statistics) An integral transform that may be regarded as the multiplicative version of the two-sided Laplace transform.

plural of transform fault

(mathematics) A transform used in Borel summation. / (mathematics) A generalization of this in Nachbin's theorem.

Synonym of Hadamard transform

(mathematics) The process of converting a discrete time-based function into its frequency-based representation.

(mathematics) 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.

A member of a certain family of algorithms for efficiently computing the discrete Fourier transform of data. / An instance of performing one of these algorithms.
