Brief description

Fourier Transform Demonstration (FTD) is an educational tool for visual interactive presentation of the Fourier transform (the transform is used in the fields like signal processing, pattern recognition, etc.). The FTD applet shows the time and the frequency domains in the wire cube at the same time (see applet). By changing the amplitudes and phase delays of sine functions, the resulting signal is changed. Different views can be achieved by rotating the wire cube. See documentation for the short user manual.

The applet has been tested with the Netscape Communicator 4.04 with JDK1.1 patch. For better experience use JIT enabled appletviewer/browser.
