This range of very sharp cut-off lowpass video filters provide solution to the problem of seperating

video from multiple audio sub carriers, stereo sound or multi-lingual transmissions with minimum

distortion.

The filter provides a maximum passband and a very sharp cut off with good stopband performance

out to 200 MHz. Time domain performance is maintained by providing group delay equalisation for

more than 93% of the passband.
