ABSTRACT:
An electronic device has an operating mode and an energy saving standby mode. The electronic device includes an input-side antenna element for receiving a signal carrying information, a receiving unit for processing the basic information carried on the signal, a voltage supply unit for providing the supply voltage required for operation, and a switching unit for switching between the operating mode and the standby mode. First, to minimize the current being drawn in the standby mode, and second to ensure quick and reliable switching from the energy saving standby mode to the operating mode as required, it is proposed that the signal carrying the information includes a number of modulated frequency bands. At least one frequency band is intended for the basic information to be processed by the receiving unit. The other frequency band contains wake-up information for actuating the switching unit.
