Abstract
The invention relates to an infrared receiver circuit for processing a carrier-modulated infrared signal, comprising an amplification circuit and a demodulator. A comparator is provided, which is designed to digitize the output signal of the amplification circuit or of a band pass filter connected downstream of the amplification circuit by comparison to a threshold value in order to create a pulse train signal. The receiver circuit comprises a logic circuit, which is designed to link the pulse train signal of the comparator and the output signal of the demodulator logically to each other in order to extract an additional output signal corresponding to the infrared signal from the pulse train signal.
