GENERAL PURPOSE LP FILTER

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.

This range may be extended up to 30 MHz. Filters with other end of passband frequencies within the range can be

supplied at no extra cost.

Order as FF****UD inserting the frequency required in place of the asterisk eg for 5.23 MHz FF0523UD.
