Detailed explanation-1: -In telecommunications and computer networking, multiplexing (sometimes contracted to muxing) is a method by which multiple analog or digital signals are combined into one signal over a shared medium.
Detailed explanation-2: -In telecommunications, frequency-division multiplexing (FDM) is a technique by which the total bandwidth available in a communication medium is divided into a series of non-overlapping frequency bands, each of which is used to carry a separate signal.
Detailed explanation-3: -Multiplexing is done in a many-to-one approach, with n input and one output line. On the receiver side, a device known as a Demultiplexer (DEMUX) divides a signal into its constituent signals (one input and n outputs). As a result, demultiplexing follows the one-to-many approach.
