Definition of "Multiplexing" |
A method for simultaneous transmission of two or more signals over a common carrier wave. The T1 Interface uses multiplexing to transmit data over trunk lines. An IC circuit that transmits one of two signals from the input to the output, refer to IC Multiplexers. Multiplexing is used when driving many single channels to a remote location, but installing a separate line for each channel would be prohibitive. / In telecommunication and computer networks, multiplexing sometimes contracted to muxing is a method by which multiple analog message signals or digital data streams are combined into one signal over a shared medium. / A computer with more than one central processor. / (1) the process of transmitting a large number of information units over a smaller number of channels or lines. For example, if we have N independent signals that we want to transmit, then without using a multiplexer we need N independent channels to do so. Using a multiplexer to control the flow of these signals in only one channel reduces the number of wires, thus decreasing cost and increasing efficiency. Multiplexing is the superimposition of multiple signals to make up one signal. This is done to make the transmission of the signals efficient. Signals are multiplexed at the sending end of communication systems, and demultiplexed at the receiving end, in order to obtain the original signals. |
