lntelvideo's Digital Co-Channel Filter Model CF110 is a state of the art signal processing system that significantly reduces co-channel interference, random noise and other video errors. It is particularly effective in reducing the 10 kHz and 20 kHz co-channel beats and restoring video synchronization even when the co-channel level is so high as to cause loss of vertical and horizontal sync in most television receivers. The Model CF110 reduces the 10 kHz and 20 kHz co-channel beats by up to 30 dB and other co-channel noise by up to 9 dB. Under extremely severe co-channel conditions the Model CF110 replaces the sync pulses with stable and clean sync.
