Abstract:
1. A data coupler, comprising: an acoustic isolation transformer operable to develop an isolated output signal in response to an input signal; a transmitter adapted to receive a data input signal and coupled to the acoustic isolation transformer, the transmitter operable to generate a continuous periodic input signal for the input signal responsive to the data input signal, wherein the transmitter utilizes one of On/Off Keying, frequency modulation, Frequency Shift Keying, amplitude modulation, and Amplitude Shift Keying to generate the periodic input signal, the transmitter being operable to start generating the periodic input signal responsive to a first transition of the data input signal from a first logic state to a second logic state and to terminate generating the periodic input signal responsive to a second transition of the data input signal from the second logic state to the first logic state; and a receiver coupled to the acoustic isolation transformer to receive the isolated output signal and operable to generate a data output signal responsive to the isolated output signal.
