ABSTRACT:
A system for delivering signal, such as video signal, over signal carrier, such as twisted-pair cable. The system includes a video source connected to a terminal of the signal carrier and providing video signals thereto. An amplifier is coupled to a second terminal of the signal carrier at the receiving end. A source reference signal generator is connected to a first terminal of a second signal carrier. A second amplifier is connected to a second terminal of the second signal carrier at the receiving end. A comparator is connected to an output of the second amplifier and a receiver reference signal. An output of the comparator is provided to a gain control of the variable gain amplifier.
