Description
the minimum signal strength the decoder will accept. If the signal
strength is below this level, it is not evaluated.
the minimum signal strength the decoder input that must be reached
by the weaker half-bit of the Manchester encoded signal to generate
a bit-collision (relative to the amplitude of the stronger half-bit)
