OK, let's try this again.
Hi I have a question on filtering out the 'herringbone' pattern that
appears on images when I use a b/w frame grabber to digitize the video
signal given by my (color) camcorder.  I know that the color signal
frequency is ~3.5 MHz, and I built a trap filter tuned to that
frequency (It works OK).  But I was wondering if there was any program
or algorithm for doing this _in software_.  Any help would be
appreciated.
