Multiplexing and demultiplexing: Definition

Definition & Basics :


 "Multiplexing is the procedure in which numerous Data Streams, originating from diverse Sources, are joined and Transmitted over a Single Data Channel or Data Stream."

Multiplexing and demultiplexing: Definition


     In Electronic Communications, the two fundamental types of Multiplexing are Time Division Multiplexing (TDM) and Frequency Division Multiplexing (FDM).



     In Time Division Multiplexing, Transmission Time on a Single Channel is partitioned into non-covered Time Slots. Information Streams from diverse Sources are partitioned into Units with same size and interleaved progressively into the Time Slots.

      In Frequency Division Multiplexing, Data Streams are conveyed all the while on the same Transmission medium by designating to each of them an alternate Frequency Band inside of the Bandwidth of the Single Channel.

       Multiplexing is finished by a hardware called Multiplexer (MUX). It is put at the Transmitting End of the correspondence join. At the Receiving End, the Composite Signal is isolated by a gear called Demultiplexer (DEMUX). Demultiplexer performs the opposite procedure of Multiplexing and courses the isolated signs to their comparing Receivers or Destinations.

      TDM interleaves little Units of every Data Stream into the relating Time Slots. It Transmits the Data Streams from three Signal Sources (Red, Green and Blue) all the while by joining them into a Single Data Stream.

Multiplexing and Multiple Access

Multiplexing And Multiple Access : Digital Communications Difference between Multiplexing and Multiple Access: Sr.No. Multiplexing Multiple Access 1 “In telecommunications and  computer networks, multiplexing is a process where multiple analog  message signals or digital data  streams are combined into one   signal over a shared medium.” “In telecommunications and computer networks, a channel access method or multiple access  method allows several terminals connected to the same multipoint physical medium to transmit over it and to share its capacity.” 2 The multiplexed signal is transmitted  over a communication channel,  which may be a physical transmission medium. A channel-access scheme is  based on a multiplex method  that allows several data streams  or signals to share the  same communication channel or  physical media.

Difference in between Time division multiplexing (TDM) and Frequency division multiplexing (FDM)

Difference in between TDM and FDM: This page on FDM versus TDM describes  difference between FDM and TDM multiplexing . FDM is the short form of frequency division multiplexing and TDM is the short form of time division multiplexing. In FDM each signal is modulated onto different unique RF carrier frequency and all carrier frequencies are separated significantly so that bandwidth of the signals do not overlap in frequency domain.
