If this is a remote control signal, with ppm, then no, you need to look at
the edges. If it's a barrier, you can look in the middle. The problem is,
that if the source is not iso-synchronous with your code, the 2 will
slowly slip out of sync (slowly is within seconds or less even with good
crystals).
