Create Simulink filter block using Realize Model panel
You must have the Simulink® product installed to use this function.
dspfwiz opens Filter Designer with the Realize
Model panel displayed.
Use other panels in Filter Designer to design your filter and then use the Realize Model panel to create your filter as a subsystem block, which is a combination of Sum, Gain, and Delay blocks, in a Simulink model.
If you also have the DSP System Toolbox™ software installed, you can create a Biquad Filter block or a Discrete FIR Filter block instead of a subsystem block, by deselecting the Build model using basic elements check box.
