LOW PASS VIDEO FILTERS
STEEPNESS FACTOR 1.35

FF….L SERIES

These low pass video filters are intended for bandwidth limitation over the video range of frequencies. The video filters are 7-pole Elliptical Function networks which have been equalised to correct for group delay distortion over 95% of the passband and for loss distortion over the entire passband.

Degradation of a composite video signal is minimal when a 4.5 MHz or 5.5 MHz filter is selected for a 525 or 625 line T.V. system. Typical uses are to suppress sound or telephone channels placed above and close to the video band. The standard filters are specified. We would be pleased to examine special requirements.
