TFTB – Time-Frequency Toolbox

The Time-Frequency Toolbox (TFTB) is a collection of about 100 scripts for GNU Octave and Matlab (R) developed for the analysis of non-stationary signals using time-frequency distributions. It is primary intended for researchers, engineers and students with some basic knowledge in signal processing.

The toolbox contains numerous algorithms which implements various kind of time-frequency analysis with a special emphasis on quadratic energy distributions of the Cohen and affine classes, along with their version enhanced by the reassignment method. The toolbox also includes signal generation procedures, processing/post-processing routines (with display utilities) and a number of demonstrations.

The TFTB is distributed under the terms of the GNU Public Licence.

The TFTB has been developed by François Auger, Olivier Lemoine, Paulo Gonçalvès and Patrick Flandrin under the auspices of the CNRS (Centre National de la Recherche Scientifique) within its GdR Information, Signal et Images. Parts of the Toolbox have also been written at Department of Electrical and Computer Engineering of Rice University with the support of the NSF.
