INTRODUCTION
multiplexing(also known as muxing) is a method by which multiple analog message signals or digital data streams are combined into one signal over a shared medium
For example, in telecommunications, several telephone calls may be carried using one wire.A device that performs the multiplexing is called a multiplexer (MUX), and a device that performs the reverse process is called a demultiplexer (DEMUX)
Demultiplexing
Inverse multiplexing (IMUX) has the opposite aim as multiplexing, namely to break one data stream into several streams, transfer them simultaneously over several communication channels, and recreate the original data stream.
