De Fourier a wavelets : un breve recorrido por el análisis tiempo-frecuencia
(2020)
Un pequeño tour por el análisis de Fourier. Definimos a la transformada continua de Fourier, presentamos y estudiamos los resultados principales de la serie de Fourier y de la transformada de Fourier discreta. Analizamos ...
A caveat about applications of the unilateral Fourier transform
(Sociedade Brasileira de Física, 2020-07-17)
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 ...

Application of block matrix theory to obtain the inverse transform of the vector-valued DFT
(Hikari Ltd., 2015)
We study the vector-valued discrete Fourier transform (vector-valued DFT) and its inverse transform, the vector-valued DFT inversion, through its block matrix representation. These transforms are defined for N- periodic ...
