#11 Software: Joint time-frequency analysis using Signalogram

The Signalogram is a PC-based software package for signal and image
visualization and analysis. It includes data wrapper classes, algorithm
management system and graphical user interface (GUI). The GUI is written for
MS Windows platforms. Such an interface enables analysis of several data
sets simultaneously, multithreading, representation of results by tables,
1D, 2D and 3D plots as well as error messaging.

The software is designed as a set of separate modules prepared using
templates and linked to the main application by means of COM technology. One
of the modules is devoted to the joint time-frequency analysis, namely, the
short-time Fourier transform, which is calculated using the discrete Gabor
transform and the discrete Zak transform according to the paper:

M. J. Bastiaans and M. C. W. Geilen, On the discrete Gabor transform and the
discrete Zak transform, Signal Process. 49 (1996), 151-166.

The package is available at:
