Examine the Parametric EQ block in a Simulink® model and tune parameters.
1. Open the Spectrum Analyzer and Parametric EQ blocks.
2. In the Parametric EQ block, click View Filter Response. Modify parameters of the parametric equalizer and see the magnitude response plot update automatically.
3. Run the model. Tune parameters on the Parametric EQ to listen to the effect on your audio device and see the effect on the Spectrum Analyzer display. Double-click the Manual Switch block to toggle between the original and equalized signal as output.
