ABSTRACT:
A calibration system for a communication system is provided featuring a transmitter circuit, a receiver circuit, a transmission medium having a transfer function for transmitting a signal between the transmitter and receiver circuits, and a calibration system responsive to the altered reference signal of the transmitter circuit for adjusting the reference signal level of one of the transmitter and receiver circuits to compensate for variations in the transmission signal due to the transfer function.
