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 and engineers with some basic
knowledge in signal processing.
The toolbox contains numerous algorithms performing time-frequency
analysis with a special emphasis on quadratic energy distributions of
the Cohen and affine classes, and their version enhanced by the
reassignment method. The toolbox also includes signal generation
procedures and processing/post-processing routines (with display
utilities).
