Frequency-Division Multiplexing (FDM)įDM or Frequency-Division Multiplexing is an analogy technology in which frequency technology is used In the following sections, we’ll go through each of the above-mentioned techniques one by one. Let’s have a look at these various types of multiplexers: There are mainly three types of techniques used in multiplexing. Multiplexing is divided into two categories i.e. Techniques of Multiplexing (Types of Multiplexer) Multiplexing aids in the efficient exploitation of the medium’s bandwidth.It allows for the transmission of numerous signals via a single medium or link.The following are some of the benefits and advantages of employing multiplexing: Must Read ➜ What is HTTP? Advantages of Multiplexing Consider a television cable distributor that distributes multiple channels over a single wire. Sending many signals in different ways is quite expensive, and it also necessitates the use of extra lines.Īs a result, multiplexing is required. When there is a requirement to send numerous signals from the sender side at the same time, a multiplexer is used to combine numerous signals into one so that we may receive them all at the same time on the receiving end. As we previously stated, multiplexing is a set of techniques that permits the transmission of many signals at the same time through a signal data link. Multiplexing in data communication systems and Computer networks is very much required. In telephony, George Owen Squier is credited with developing telephone carrier multiplexing in 1910.This method is now frequently used in telecommunications.Multiplexers were also invented in the 1870s in telegraphy.Several telephone calls can be carried over a single line in telecommunications.Multiplexers in Computer Networking has a long and illustrious history.As a result, a single link can have several channels. The term link refers to the physical path in the figure above, while the term channel merely refers to the segment of the connection that conducts a transmission between two lines.

Let’s look at how to partition one link into n channels using the diagram below:

The main objective of using the multiplexer technique is to share scarce resources. This stream is routed into the demultiplexer (DEMUX) on the receiver side, which divides the stream into its component transmissions (one-to-many) and directs them to their associated lines. On the sender side, the Multiplexer (MUX) primarily mixes ‘n’ input lines in order to generate a ‘1’ output line (this is simply many-to-one).

What is Multiplexer and how it works?Ī multiplexer (MUX) is a device that allows digital information from several sources to be routed onto a single line for transmission over that line (medium) to a common destination. Multiplexing is a technique where several users use the medium simultaneously without interference or with minimum interference. Multiplexing is a process of sending the number of separate signals together over the same cable or bearer, simultaneously and without interference. Multiplexing is accomplished with the help of a piece of hardware known as a multiplexer (MUX). Multiplexing in Computer Networks is a term used to describe a collection of procedures that permits several signals to be sent over a single data link at the same time. In this article, You will also learn the definition, importance, benefits, techniques, and different types of Multiplexing such as FDM, WDM, TDM, and their uses. We have shared all the basic information about MUX used in networking. We’ll go through the notion of multiplexing in computer networks in this tutorial.
