INFRARED REMOTE CONTROL SIGNAL PROCESSING CIRCUIT

摘要

The invention relates to an infrared remote control signal processing circuit for processing a remote control signal. The processing circuit comprises within an integrated circuit a first and a second reception channel. The first reception channel is provided with a bandpass filter with a bandpass frequency that corresponds to a predetermined carrier frequency of the remote control signal. The second reception channel has no frequency filter or at least a filter with a wider bandpass range than the first reception channel. The two reception channels have respective allocated signal outputs for connection to an evaluation circuit.
