FARADAY STEP FILTER VERY FAST CUT OFF LOWPASS VIDEO FILTER 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.
