FF….P SERIES
LOW PASS VIDEO FILTER
STEEPNESS FACTOR 1.14
These low pass video filters are intended for bandwidth limitation over the video range of frequencies where it is required to attenuate frequencies close to the edge of the passband. The filters are 9-pole Elliptical Function networks which have been equalised to correct for group delay distortion over 80% 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.
