Description

The Time-Frequency Signal Analysis (TFSA) package is a general purpose tool for scientific and signal processing applications. TFSA enables the user to quickly and easily apply time-frequency and time-scale representations, instantaneous frequency estimators and other tools. The TFSA package was first developed as a set of algorithms in FORTRAN as described in chapter 7 of Time-frequency Signal Analysis - Methods and Applications (Longman Cheshire, 1992, B. Boashash editor). Previously available as computational routines written in C, the TFSA package is now distributed as a MATLAB toolbox. In addition to the plotting facilities of MATLAB, a graphic user interface has been added to make the package more accessible to new users. The latest version of the TFSA package is available as precompiled MEX files for the following operating systems:

UNIX (Solaris)       LINUX (RedHat)      WINDOWS NT/98/95

UNIX (Digital Unix V4.0)(ALPHA processor)

The latest version of the TFSA package, version 5.2 is now available. Features of the package include:

• A powerful graphical user interface (GUI).
• A large class of bilinear and multi-linear time-frequency representations
• Time-scale and scale-domain analysis.
• Instantaneous frequency estimators.
• The ability to read and write using ASCII and MATLAB data formats.
• The capability to invoke these algorithms via MATLAB-callable. functions for inclusion in larger simulations.
• Powerful data visualisation tools.
• Default parameter values could be set easily by the user.
• Full documentation is available.
