In [[telecommunicationtelecommunications]] and [[computer data storage|data storage]], '''Manchester code''' (also known as '''phase encoding''', or '''PE''') is a [[line code]] in which the encoding of each data [[bit]] is either low then high, or high then low, for equal time. It is a [[self-clocking signal]] with no [[DC component]]. Consequently, electrical connections using a Manchester code are easily [[galvanic isolation|galvanically isolated]].
Manchester code derives its name from its development at the [[University of Manchester]], where the coding was used for storing data on the magnetic drums of the [[Manchester Mark 1]] computer.
