Date Aug. 17, 1995A radiation emitting device, such as an LED, is optimally driven in dependence on the value of a carrier frequency of a signal to be transmitted. The current provided to the radiation emitting element is controlled responsive to the carrier frequency. When using an LED, the current value is increased with decreasing duration of current flow. The apparatus is usable for remote controls suitable for controlling two or more devices.
