FLB... SERIES
GENERAL PURPOSE LP FILTER
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 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.
