  • Transmission of signals through a non-contact interface
    Patent number: 9633783
    Abstract: A bi-directional transmission system for transmission of signals through a non-contact interface includes a transformer inductively coupling a first circuit to a second circuit. The second circuit includes at least a first transmitter circuit arranged to translate a first digital input signal into at least one voltage pulse and to provide the at least one voltage pulse to a first winding of the transformer, wherein the at least one voltage pulse takes a positive or negative form based on whether the first digital input signal has a positive or negative edge. The first circuit includes at least a first receiver circuit arranged to receive at least one induced voltage pulse from a second winding of the transformer and to provide a first digital output signal reflecting the first digital input signal based on the at least one induced voltage pulse.
