ABSTRACT:
A driver circuit for driving a light emitting element with a signal generated by superimposing an analog sub-information signal over the pulse string of a digital main signal. The driver circuit includes an input interception detector for detecting any interception of the digital main signal, and a gain-controlled amplifier for increasing the gain of the analog sub-information signal when the digital signal is intercepted.
