MULTIPLEXING AND DEMULTIPLEXING Gaurav Dronacharya College Of Engineering , Gurgaon Abstract- In telecommunications 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. Modulation is varying the properties of a career signal to send information, whereas multiplexing is a way of combining multiple signals. In this technique, time intervals are used to merge signals. Multiplexing –. The process of multiplexing divides a communication channel into several number of logical channels, allotting each one for a different message signal or a data stream to be transferred. To make more cost-effective, the transport layer sends several transmissions bound for the same destination along the same path; this is achieved through upward multiplexing.
