Model Gaussian Filter in Simulink

Use the gaussdesign function with the Discrete FIR Filter block to model Gaussian filtering in Simulink®.

The model configures Gaussian filtering to show peak amplitude normalization, filter energy normalization, and sum of coefficient normalization. Coefficients in the Discrete FIR Filter blocks are calculated in the block mask or in the model preload callback. From the model menu, navigate to File -> Model Properties -> Model Properties -> Callbacks.

Plot to compare the filter response for the three normalization configurations.
