Note
Miller Encoding Definition:
Miller encoding will encode a “1” as a phase
transition in the middle of a data period. A “0” is
encoded the same as the previous bit. This means
that only a “1” causes the data to transition from
high or low.

Manchester Encoding Definition:
Manchester encoding encodes a “1” or “0” on
each transition in a data period. The Manchester
definition used for the GSP-9300 uses a low to high
transition to indicate “0”, and a high to low
transition to indicate 1”.
