The easiest way to input IRIG-B is as an audio signal via a
soundcard, and use a software decoder. That was one my first
jobs when I joined Alcatel Space more than 10 years ago :-)
We are still using that code -- it takes less than 0.1% of
available CPU on today's systems, and provides sub-microsecond
accuracy.
