Wavelets
| Wavelet Transform Engine
|
Update Link / Bad Link? |
|
This Java applet serves as a wavelet transform engine. You can load your own signal by choosing one of the menus. The wavelet transform of the signal will be computed. Then you can save those coefficients in order to process them using whatever method you like. Finally you can load the processed coefficients into the applet to do the inverse transform.

| Wavelet based Compression
|
Update Link / Bad Link? |
|
This applet shows the basic idea of wavelet based lossy compression. First you choose a signal and a wavelet. The wavelet coefficients of the signal are shown in the figure at the left hand side.

| Fourier series approximation plot
|
Update Link / Bad Link? |
|
This plot shows a sequence of approximations to a square wave constructed by adding together sinusoids. It is implemented by a Java class derived from Plot that computes the data to be plotted on the fly.
