ABSTRACT:
A noise trap circuit which suppresses noise in a communication system of the type used in hotels and motels to transmit encoded communication signals such as room status information. The communication signals are transmitted on the neutral and ground lines of the AC power distribution network of the building. The noise trap circuit is an LCR circuit connected between the hot and neutral lines. The capacitor and inductor of the LCR circuit pass the communication signal band width, and the resistor has an impedance equal to the line impedance with the offending noise sources active. The communication system normally has a remote controller in each room of the building, and each remote controller is equipped with a noise trap circuit.
