Figure 11. Biquad GUI Window

A check mark selects the Biquad. If not selected, the Biquad is in ALL PASS Mode.

The frequency response and phase response plots for the current settings can be viewed and adjusted in the Frequency Response and Phase Response panes of the Biquad GUI as shown in Figure 11. The individual Biquad gains must be within ±12db.

Clicking the Apply & Draw button sends all three banks of coefficients to the Frequency Response and Phase response plots (providing auto bank is enabled).
