FF0250J

FF…J SERIES GENERAL PURPOSE VIDEO FILTER STEEPNESS FACTOR 1.32 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 and at a reduced cost. The filters are corrected for group delay distortion over 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.
