This Xcos toolbox is aimed at filtering a signal based on the wavelet theory.
The algorithm used here is recursive. Thus it could be used in embedded
On top of the toolbox tree files, you will find a help pdf
"HelpLeftWaveDenoise.pdf" which explains how to set the 3 parameters
(delay, scale, threshold) used to filter the signal.
An example has been provided in the demonstration tab.
The advantage of such a filter against low pass filters is that this filter is
much more reactive and let you follow a tendency more easily and more
This toolbox is also a way to learn how to port a Matlab S-Function used in a
Simulink model into a Scilab/Xcos block.
