3. Error Correction circuitry:
Xantech IR receivers actively monitor and confirm an infrared signal’s validity by comparing it to typical
remote control signal patterns, using an advanced digital correction circuit. By doing this, unwelcome
spurious or very high-frequency interference are ignored, while validated (but distorted) IR signals are
quickly repaired and purged of undesirable noise.
4. Native Carrier Frequency Integrity:
Nearly every IR system relies on a carrier frequency to “carry” the commands from a remote control to a
controlled system component. Some consumer electronic devices, especially newer digital cable and satellite
TV boxes, are very picky regarding carrier frequency accuracy: they may not accept remote commands unless
they can “see” precisely the right carrier frequency. The challenge is that both distance and ambient lighting
can degrade the critical carrier frequency.
