Noise trap arrangement for AC power line communication systems

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