multiplexing |
1 definition found From The Free On-line Dictionary of Computing (13 Mar 01) [foldoc]: multiplexing(Or "multiple access") Combining several signals for transmission on some shared medium (e.g. a telephone wire). The signals are combined at the transmitter by a multiplexor (a "mux") and split up at the receiver by a demultiplexor The communications channel may be shared between the independent signals in one of several different ways: {time division multiplexing}, {frequency division multiplexing} or {code division multiplexing}. If the inputs take turns to use the output channel ({time division multiplexing}) then the output bandwidth need be no greater than the maximum bandwidth of any input. If many inputs may be active simultaneously then the output bandwidth must be at least as great as the total bandwidth of all simultaneously active inputs. In this case the multiplexor is also known as a {concentrator}. (1995-03-02)
