STEEPNESS FACTOR 1.35

These low pass video filters are intended for bandwidth limitation over the video range of frequencies. The filters are

7-pole Elliptical Function networks which have been equalised to correct 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. Typical uses are to suppress sound or

telephone channels placed above and close to the video band. The standard filters are specified. We would be pleased

to examine special requirements.
