This button allows the user to view the composite filter response in
either a magnitude vs. frequency or phase vs. frequency
environment. Clicking on the button will toggle the setting.

This button allows the user to view the composite filter response in
either a logarithmic or linear environment. Clicking on the button will

Using the 24 dB, 40 dB, 120 dB Controls
These buttons allow the user to view the composite filter response in
three different dynamic ranges. Clicking on one of the buttons will set
the dynamic range.
Gain Trim
The Gain Trim can be used to shift response up or down. This is
especially useful with shelving filters. With shelving filters in a boost
situation, an amount of gain trim equal to the amount of boost should
be added. Gain trim does not need to be added in the case of a
shelving filter with cut. The Gain Trim can be adjusted two ways:

numbers in the box next to the slider will change. When the
desired level is reached, release the mouse button.
