List Of Fourier-related Transforms




This is a list of Linear Transformation s of Function s related to the Fourier Transform . Such transformations map a function to a set of Coefficient s of Basis Function s, where the Basis Function s are Sinusoidal and are therefore strongly localized in the Frequency Spectrum . (These transforms are generally designed to be invertible.) In the case of the Fourier transform, each basis function corresponds to a single Frequency component.

Applied to functions of continuous arguments, Fourier-related transforms include:


For usage on Computer s, number theory and algebra, discrete arguments (e.g. functions of a series of discrete samples) are often more appropriate, and are handled by the transforms (analogous to the continuous cases above):


The usage of all of these transforms is greatly facilitated by the existence of efficient algorithms based on a Fast Fourier Transform (FFT). The Nyquist-Shannon Sampling Theorem is critical for understanding the output of such discrete transforms.
