On Katugampola Fourier Transform [PDF]

open access: yesJournal of Mathematics, 2019
The aim of this article is to introduce a new definition for the Fourier transform. This new definition will be considered as one of the generalizations of the usual (classical) Fourier transform.

Fractional Fourier Transform: Main Properties and Inequalities

open access: yesMathematics, 2023
The fractional Fourier transform is a natural generalization of the Fourier transform. In this work, we recall the definition of the fractional Fourier transform and its relation to the conventional Fourier transform.

A caveat about applications of the unilateral Fourier transform [PDF]

open access: yesRevista Brasileira de Ensino de Física, 2020
It is presented a warning about the erroneous use of unilateral Fourier transform with nonhomogeneous Dirichlet or Neumann boundary conditions in a well-known textbook on integral transforms, and also in a few papers recently diffused in the literature.

Radar matched filtering using the fractional fourier transform [PDF]

open access: yes, 2010
-A matched filter is the optimal linear filter for maximizing the signal to noise ratio (SNR) in the presence of additive noise. Matched filters are commonly used in radar systems where the transmitted signal is known and may be used as a replica to be ...

More on the quantum harmonic oscillator via unilateral Fourier transform [PDF]

open access: yesRevista Brasileira de Ensino de Física, 2022
The stationary states of the quantum harmonic oscillator are properly determined by means of the unilateral Fourier transform without having to recourse to the properties of the confluent hypergeometric functions. This simpler procedure is reminiscent of
