As part of continual product improvement the specifications, details and dimensions shown in this publication are subject to change without notice FARA039d Page 1 of 2 Dec-99 (C) STEEPNESS FACTOR 1.35 This range of 7-pole Elliptical Function Low Pass Filters is similar to a type which has been successfully used in broadcasting for many years but is offered in a small size with improved group delay and amplitude ripple. The filters are corrected for Group Delay distortion over approx. 95% 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.
