That causes a transformation; causing a notable and lasting change

Of, pertaining to or leading to transformation.

a big change in form, appearance, or character

(mathematics) A transform that converts a discrete time-domain signal into a complex frequency-domain representation.

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

(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.

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

Synonym of Hadamard transform

(mathematical analysis, harmonic analysis, physics, electrical engineering) A particular integral transform that when applied to a function of time (such as a signal), converts the function to one that plots the original function's frequency composition; the resultant function of such a conversion.
