FBS Fixed Filters

Fixed filters are notch filters with an adjustable center frequency and Q, and up to 30 dB of cut. The fixed filters are typically set by converting dynamic filters to fixed, however adjustments to filter parameters can be made manually from the Fixed Filters tab.

Fixed Filters are inactive and the filter type is set to Unused by default.

Figure 35. FBS Fixed Filters Tab

No filter parameters are displayed when the filter type is set to Unused. As a filter is moved to the fixed filter tab from a dynamic filter, the filter becomes active and displays Notch as the filter type. The parameters copied from the dynamic filter are displayed in the same line. Once a fixed filter is active, settings can be modified or adjusted if needed. Fixed filters can also be individually bypassed by clicking the Bypass button.
