S17 SERIES
GENERAL PURPOSE LP FILTER
STEEPNESS FACTOR 1.72
This range of 5-pole Elliptical Function Low Pass Filters is intended for bandwidth limitation with minimal
distortion of the transmitted signal. The modest rate of cut off minimises time domain ringing The filters are
corrected for Group Delay distortion over 92% of the passband and for loss distortion over the entire
passband. Degradation of a composite video signal is small when a 4.5 MHz or 5.5 MHz filter is selected for a
525 or 625 line T.V. system.
