- ##### todo: check if ir carrier frequency detection can be used
- #
- # Detect changes in the presence of an active input signal.
- # The decoder can either be fed an already filtered RX signal
- # or optionally can detect the presence of a carrier. Periods
- # of inactivity (signal changes slower than the carrier freq,
- # if specified) pass on the most recently sampled level. This
- # approach works for filtered and unfiltered input alike, and
- # only slightly extends the active phase of input signals with
- # carriers included by one period of the carrier frequency.
- # IR based communication protocols can cope with this slight
- # inaccuracy just fine by design. Enabling carrier detection
- # on already filtered signals will keep the length of their
- # active period, but will shift their signal changes by one
- # carrier period before they get passed to decoding logic.
