S14 SERIES
GENERAL PURPOSE LP FILTER
STEEPNESS FACTOR 1.40
This range of 7-pole Elliptical Function Low Pass Filters is intended for bandwidth limitation with minimal
distortion of the transmitted signal. The filters are corrected for Group Delay distortion over approx. 92% 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. The filters may be
used for antialiasing in A-D and D-A systems.
