A COMPUTATIONAL ENVIRONMENT FOR THE ANALYSIS OF DISCRETE TIME DISCRETE FREQUENCY TIME-FREQUENCY SIGNALS

There are several engineering and scientific areas where the development of meaningful applications require the analysis and design of signals whose spectral characteristics change with respect to time. The tools used to treat these signals are known as “time-frequency tools”. This on going work presents the development of a computational environment that makes a uniform characterization of time-frequency signal analysis tools through a MATLAB environment to study the spectral content of time-varying signals on a specific applications. 1
