In [[telecommunication]] and [[computer data storage|data storage]], '''Manchester codingcode''' (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, offor equal time. It thereforeis has no [[DC bias]], and isa [[self-clocking signal|self-clocking]],whichwith means that it may beno [[InductiveDC coupling|inductivelybias]] or [[Capacitive coupling|capacitively]] coupled, and that a [[clock signal]] can be recovered from the encoded data. As a result, electrical connections using a Manchester code are easily [[galvanic isolation|galvanically isolated]] using a [[network isolator]]—a simple one-to-one [[isolation transformer]].
