Trying to think up a way to 'log' an NTSC video signal- just the horizontal sync pulse from front to back porch (don't need the rest of the sig for analysis). I'd like to be able to buffer 2 or 3 samples, dump and compare (I know they should be the same....).
Any help/schem/component suggestions would be appreciated.
thanks
