ABSTRACT:
A receiver circuit uses switched capacitor circuits to couple signals received over a communication facility to connected apparatus. During a first time interval a capacitor is connected across each lead of a facility to sample the facility voltages. During a second time interval these capacitors are disconnected from the facility lines and reconnected in series as the input to a voltage regenerator circuit. The regenerator circuit reconstructs the received signals for output to connected apparatus.
