Mulitplexer (MUX)

A multiplexor, in telecommunications, is a device which combines multiple analog message signals or digital data streams into one signal. This is called multiplexing. The multiplexed signal is transmitted over a communication channel which divides the capacity of the communication channel into several logical channels, one for each message signal or data stream to be transferred. A reverse process, known as demultiplexing, extracts the original channels at the receiver end.
