FSF0420 through FSF0610

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.
