FF….M SERIES
LOW PASS VIDEO FILTER
STEEPNESS FACTOR 1.14
This range of Elliptical Function Low Pass filters is intended for bandwidth limitation where a fast rate of cut off is
required. It is especially useful in removing sound sub-carriers from a video signal while maintaining essential
bandwidth. The filters are corrected for group delay distortion over 85% 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.
