Start by creating a new model window. If it is not already done, open the Simuwave library. Double click on the block named "Shells". This will open a model (not a library) where you will find a black called "Wavelet filters". Drag and Drop it (or use Copy and Paste) into you new model window. This is the shell into which you will put all of your SimuWave blocks.
The reason for this is that all of the wavelet processing in SimuWave requires a pair of perfect reconstruction filter banks to work. These filters are generated by the mask of the "Wavelet filters" block and they are available to the blocks within. Putting all of your blocks inside "Wavelet filters" ensures the consistency of your wavelet data: they will use the same filters, same time step etc...
Here is the block's interface:
The popup menu lets you specify which wavelet class you wish to use.
You specify below the scale depth which will be used in your filter cascades.
The input sample times is the base sampling interval of the discrete data to be processed. Typically, you will use a block sampler on a continuous timle signal at the corresponding rate before processing it with SimuWave blocks.
The number of vanishing moments completely determines the filters in the wavelet class specified by the popup menu. For orthogonal wavelets (e.g., conjugate mirror filters), the second moment parameter is ignored.
The checkbox at the bottom allows you to plot the wavelets and scaling functions every time the settings are modified. May may get tired of this rather quickly.
Use the menus or the "Wavelet Filters" block's contextual menu to select the item "Look Under Mask". This will open the block and you will be able to build you wavelet processing system inside.
