FBS Fixed Filters Tab
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 manually made from the Fixed Filters tab.
Fixed Filters are inactive and the filter type is set to Unused by default (see rows 4 and 5 in
figure 43).
Figure 43. 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 as needed. Fixed filters can
also be individually bypassed by clicking Bypass.
