Why is Synchronization a problem in data communication?
synchronization between the multiplexer and demultiplexer is a
major issue in data transmission. if the multiplexer and
demultiplexer are out of synchronization a bit belonging to one
channel may be received by the wrong channel. for dis reason , one
or more synchronization bits are usually added to the beginning of
each frame. these bits, called framing bit , follow a pattern,
frame to frame, that allow the demultiplexer to syncronize with the
incoming steam so that it can separate the time slots accurately.
in most cases, this syncronization information consists of one
bit
