Networks: Data Encoding

11

Differential Manchester encoding

mid-bit transition is ONLY for clocking.

Differential Manchester is both differential and bi-phase.

Note – the coding is the opposite convention from NRZI.

Used in 802.5 (token ring) with twisted pair.

* Modulation rate for Manchester and Differential Manchester is twice the data rate inefficient encoding for long-distance applications.

1 absence of transition at the beginning of the bit interval

0  presence of transition at the beginning of the bit interval
