STEEPNESS FACTOR 1.14

These low pass video filters are intended for bandwidth limitation over the video range of frequencies where it is

required to attenuate frequencies close to the edge of the passband. The filters are 9-pole Elliptical Function networks

which have been equalised to correct for group delay distortion over 80% 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.
