Abstract
Systems, devices, and methods for isolating digital signals are described. A carrier signal can be modulated using a first signal to generate a first modulated signal. The carrier signal and the first modulated signal can be transmitted through a forward path in an isolation barrier, where transmitting the carrier signal through the isolation barrier can transform the carrier signal into a delayed carrier signal. The first modulated signal can be demodulated to recover the first signal. The delayed carrier signal can be modulated using a second signal to generate a second modulated signal. The delayed carrier signal and the second modulated signal can be transmitted through a return path in the isolation barrier, where the return path and the forward path has opposite directions.
