Signal Processing Toolbox

Analyzing the Filter

Once you've designed the filter, you can view the following filter response characteristics in the display region:

• Magnitude response
• Phase response
• Overlaid magnitude and phase responses
• Group delay
• Impulse response
• Step response
• Pole-zero plot

You can also display the filter coefficients in this region.

You can access the analysis methods as items in the Analysis menu, or by using the toolbar buttons.

For example, to look at the filter's magnitude response, select the Magnitude Response button

on the toolbar.
