ABSTRACT:
The remote control receiver comprises one or more photodiodes. The signal from the photodiodes is amplified and fed to a processing unit. The processing unit is based on a conventional integrated remote control receiver circuit, which is suited to process a remote control signal. Such integrated receiver circuits are, however, not designed to process a signal from a preamplifier. Rather, their input must be connected directly to a photodiode. By applying a replacement load instead of a photodiode to the input of the integrated receiver circuit, it becomes possible, however, to feed any electrical signal to the integrated circuit. In this way the signal can be filtered and amplified before being sent to the integrated circuit, which allows a considerably higher receiver sensitivity to be reached.
