- A communications format in which each bit is split into two, providing a self-synchronizing data stream. A 1-bit is transmitted with a high voltage in the first period and a low voltage in the second, with a 0-bit being the converse. One advantage of this encoding is that the difference between a 0-bit and no signal is distinguished, as there is no transition in the latter case. A disadvantage is that it occupies twice the bandwidth. Also called Manchester code, or Manchester encoding.
