1. A system for providing power through a power cable comprising:

  • comparator logic circuitry configured to compare a received communication signal to a reference signal, wherein the received communication signal is received from the power cable;

    biasing elements configured to create hysteresis between the reference signal and the received communication signal;

    amplification logic circuitry configured to amplify the received communication signal and output a corrected output signal in accordance with the created hysteresis between the reference signal and the receive communication signal; and

    a power supply configured to decode the corrected output signal output by the amplification logic circuitry and adjust a power output to the power cable responsive to the corrected output signal.
