    What is a discrete code?

    Published on 2017-02-28

    It is a version of a toggle code that only performs one function. Some examples would be “POWER ON” and “POWER OFF” or “VCR”, “TUNER” and “DVD” receiver inputs. These types of signals are most often used to ensure your home theater components stay completely in synchronization for powering on and off and changing device inputs.
