'''
This protocol decoder tries to guess the bitrate / baudrate of the
communication on the specified channel. Typically this will be used to
guess / detect the baudrate used in a UART communication snippet, but it
could also be used to guess bitrates of certain other protocols or buses.

It should be noted that this is nothing more than a simple guess / heuristic,
and that there are various cases in practice where the detection of the
bitrate or baudrate will not necessarily have the expected result.

The precision of the estimated bitrate / baudrate will also depend on the
samplerate used to sample the respective channel. For good results it is
recommended to use a logic analyzer samplerate that is much higher than
the expected bitrate/baudrate that might be used on the channel.
