Re: Phev Insight
Can you use input filtering by using a digital pulse filter that requires an input pulse of a specified length before it generates one. The spikes would all be eliminated if you adjusted the input to require a pulse of just short of the actual data pulse length. I am assuming of course that the data pulses are much longer than the spikes. This kind of filtering is much more effective than cap/res/ind filtering and much more effective that shielding. You could use a hex chip that could filter 6 lines all at once. It requires very little circuitry, maybe one or two chips and a few resistors to set the pulse width.
