MULTIPLEXER APPARATUS HAVING NBMB CODER

摘要

The multiplexer combines a plurality of input data bit streams into a single output bit stream. It comprises synchronizers (101 to 106) each of n input data bit streams to produce n synchronized bit streams; a coder (130) for converting mutually corresponding parallel n bits of said n synchronized bit streams into parallel m bits to produce m synchronized bit streams and a means (140) for multiplexing said m synchronized bit streams into a single high-speed output bit stream. This multiplexer requires neither an n bit serial-to-parallel converter nor an m bit parallel-to-serial converter. The dispensation with such converters, which would need high-speed operation, leads to less expensive and more compact hardware.
