STEEPNESS FACTOR 1.72

This range of 5-pole Elliptical Function Low Pass Filters is intended for bandwidth limitation with minimal

distortion of the transmitted signal. The modest rate of cut off minimises time domain ringing The filters are

corrected for Group Delay distortion over 92% of the passband and for loss distortion over the entire

passband. Degradation of a composite video signal is small when a 4.5 MHz or 5.5 MHz filter is selected for a

525 or 625 line T.V. system.
