4.4: GENERAL FILTER CONTROL WINDOWS

This section provides detailed description of the control window for each type of processing that the

PCAP II Plus implements in the General Filter, Broadband Filter, and Equalizer processing stages. For

any Filter or Equalizer block, the control window for the selected filter is accessed by clicking on the

Config button.

4.4.1: Ref Canceller Filter

Application:

The Ref Canceller adaptive filter is used to automatically cancel from the Left channel (or

“Primary”) input any audio which matches the Right channel (or “Reference”) input. For

example, the Primary (Left) input is microphone audio with desired voices masked by radio or

TV sound. The radio/TV interference can be cancelled in real-time if the original broadcast

audio, usually available from a second receiver, is simultaneously connected to the Reference

(Right) input.
