ABSTRACT:
In a remote control system which generates a remote control signal by a temporary short-circuit on the secondary side of a transformer during an influencing period or time span about a zero point transition of the alternating-current mains voltage, a considerable improvement in the receiver-side recognition or detection of the remote control signal can be accomplished by a different determination, in relation to the prior art, of the receiver-side comparison period as concerns its start and duration. There is correlated the comparison period to the course of the receiver-side alternating-current mains voltage before the mains voltage zero transition to be monitorerd. This system may be used in remote control technology using signal transmission on a power supply network.
