Synchronous Xmission
Synchronous Xmission
For example, in self-clocking codes, (i.e.
FM-0, a biphase space code used in
localtalk) each bit cell contains a
transistion at each end that provides timing
information know as one bit-time.
Zeros are encoded by adding a transition at
midcell.
An alternative is to Xmit clock on a
different channel than the data (extra wire).
