Abstract
Systems and methods pertaining to propagation of digital data from a transmit side domain to a receive side domain through an intermediate isolation barrier are described. Specifically, a carrier waveform is superimposed upon a first logic level of a digital signal that is referenced to a first local ground. The digital signal with the superimposed first carrier waveform is propagated through the intermediate isolation barrier. On the receive side domain, the propagated digital signal is processed using a second local ground that is different than the first local ground, the processing including the use of the carrier waveform to enforce the first logic level upon an output digital signal generated from the propagated digital signal.
