Description
The FMS6406 is a dual Y/C 5th order Butterworth lowpass video filter optimized for minimum overshoot and flat group delay. The device also contains a summing circuit to generate filtered posite video, an audio trap and group delay pensation circuit. The audio trap removes video information in the spectral...
