Tracking filter

When opening a new Frequency integration, derivation math function the following setup window will appear:

Tracking filter has a center frequency that is always tuned to the current drive frequency. This allows att other signals to be rejected from measurement and control.

Tracking filters greatly reduce the noise and harmonic signals above and below the signal’s center frequency. The narrower the bandwidth of the tracking filter. the more the rejection of harmonics and noise outside of the filter’s bandwidth.
