multiplexing

multiplexing,

in communication, technique whereby two or more independent messages, or information-bearing signals, are carried by a single common medium, or channel. When multiplexing is performed, two or more channels are combined into a single channel, or, in a process often called demultiplexing, a single channel is divided into several subchannels. Many different types of multiplexing are possible. One type is frequency-division multiplexing, in which a single frequency channel is subdivided into two or more subchannels, each of which can then carry a smaller range of frequencies than could the original channel. Frequency-division multiplexing is used in television broadcasting, when audio and video signals share a single channel; in stereophonic FM radio broadcasting, when two audio signals share a single channel; and in microwave transmission of long-distance telephone calls, when 60 or more conversations are carried by a single microwave beam. A second type of multiplexing is time-division multiplexing, in which successive small time intervals are used for the transmission of messages over a single channel. Time-division multiplexing is often used in the construction of digital computers. When information can be stored into or retrieved from the computer's memory at a much greater rate than it can be supplied or used by an external device such as a card reader, printer, or teletype terminal, several such low-speed devices can share a single multiplexed data channel.

multiplexing

[′məl·tə‚pleks·iŋ] (communications) A set of techniques that enable the sharing of the usable electromagnetic spectrum of a telecommunications channel (the channel pass-band) among multiple users for the transfer of individual information streams. In particular, the case in which the user information streams join at a common access point to the channel.

multiplexing

1. (Or "multiple access") Combining severalsignals for transmission on some shared medium (e.g. atelephone wire). The signals are combined at the transmitterby a multiplexor (a "mux") and split up at the receiver by ademultiplexor. The communications channel may be sharedbetween the independent signals in one of several differentways: 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 nogreater than the maximum bandwidth of any input.

If many inputs may be active simultaneously then the outputbandwidth must be at least as great as the total bandwidth ofall simultaneously active inputs. In this case themultiplexor is also known as a concentrator.

multiplexing

Transmitting several signals over a single communications line or computer channel. The two common techniques are frequency division multiplexing (see FDM), which separates signals by modulating the data onto different carrier frequencies, and time division multiplexing (see TDM), which separates signals by interleaving bits one after the other. See modulation, carrier, subcarrier, FDMA and TDMA.
