GENERAL PURPOSE LOW PASS FILTERS

FLB... SERIES

STEEPNESS FACTOR 1.45

This range of 7-pole Elliptical Function Low Pass Filters is derived from a well proven, versatile design for high transparency applications but is offered in a reduced size. The low pass filters are corrected for Group Delay beyond the passband edge (104%) thus minimising time domain ringing 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.
