It explains how to use the Fourier matrix to extract frequency information from a digital ... through examples and computer explorations how these transforms are used in signal and image processing.

Abstract: The discrete Fourier transform (DFT) produces a Fourier representation for finite-duration data sequences. In addition to its theoretical importance, the DFT plays a key role in the ...

Abstract: The nonuniform discrete Fourier transform (NDFT) of a sequence of length N is defined as samples of its z-transform evaluated at N distinct points located arbitrarily on the z-plane. The ...
