John,
I am not sure this is relevant, but often more than one data inut can be
transmitted on a single wire like speed and azimuth, where speed is derived
as an ac signal (pulse rate) It could be riding on top of a dc reference
voltage used in azimuth calculation. These two pieces of intelligence could
easily be separated using capacitive coupling at the receiver.
