Abstract
When a light-emitting diode is controlled for transmitting high-frequency signals, such as video signals, or quick-changing analog signals, the electro-optical signal conversion is subjected to distortions due to temperature variations in the barrier layer of the diode which arise due to rapidly varying power losses. The circuit presented herein includes a compensating stage operatively connected to the diode, for alleviating such signal distortions. The system is capable of differentiating between the respective conditions of rising and falling edges of the control in the representative signal of signals to be transmitted.
