File Information

RF Blockset converts frequency domain RF information to a baseband-complex time-domain model, for fast execution and compatibility with Simulink signal processing and communications blocks.

This simple model illustrates some relationships inherent in the conversion...

* Length of impulse response = number of sub bands

* Total bandwidth = 1/sample time

* sub band bandwidth = total bandwidth / number of sub bands

Select "View=>Model Explorer" on the Simulink menu to view and change the n_sub_bands and bandwidth parameters in the Model Workspace, then rerun the model to see the effect
