On the Integrability and Uniform Convergence of Multiplicative Fourier Transforms

Georgian Mathematical Journal, 2009
Abstract Analogues of two Hardy–Littlewood theorems are proved for a multiplicative Fourier transform. A Szasz type condition for a multiplicative Fourier transform is given and its nonimprovability is proved. Besides, an analogue of Ul'yanov's theorem on the uniform convergence of a trigonometric series and an analogue of Konyuškov ...

Multiplicative Fourier Transform Algorithm

open access: yes, 1997
The Cooley-Tukey FFT algorithm and its variants depend upon the existence of nontrivial divisors of the transform size N. These algorithms are called additive algorithms since they rely on the subgroups of the additive group structure of the indexing set.

Reducing Inter-Replicate Variation in Fourier Transform Infrared Spectroscopy by Extended Multiplicative Signal Correction

open access: yesApplied Spectroscopy, 2009
Fourier transform infrared (FT-IR) spectroscopy is a powerful tool for characterizing biological tissues and organisms, but it is plagued by replicate variation of various sources. Here, a method for estimating and correcting unwanted replicate variation

Asymptotic Expansion of Multiple Fourier Transforms

SIAM Journal on Mathematical Analysis, 1979
Asymptotic expansion of multi-dimensional Fourier transforms is derived. An explicit expression for the remainder term is also given, from which an error bound can readily be obtained.

Multiplicity of fractional Fourier transforms and their relationships

IEEE Transactions on Signal Processing, 2000
Summary: The multiplicity of the fractional Fourier transform (FRT), which is intrinsic in any fractional operator, has been claimed by several authors, but never systematically developed. The paper starts with a general FRT definition, based on eigenfunctions and eigenvalues of the ordinary Fourier transform, which allows us to generate all possible ...
