It's an automotive application - measuring wheel speed and engine RPM (among
other things), so I'm guessing the pulse train is going to be in the 0 to
100Hz range.  Not sure about pulse width - haven't thought that far ahead.

What are the characteristics of the pulses? Frequency, duty cycle, etc? How
is the information transmitted? How often?
