What is multiplexing why is multiplexing needed in electronics communication?
multiplexing refeers to the transmission of different signals in the same channel simultaneously. There are many forms of multiplexing that can be used, including frequency division multiplexing(FDM) where individual signals are transmitted over adjacent , non overlapping frequency bands. they are transmitted in parallel and simultaneously in time. In time division multiplexing(TDM) each signal is allowd to use the whole bandwidth for a certain period of time. Multiplexing is needed so that the available channel can be used efficiently and also to save costs. There is too much to know about multiplexing, here is just a short overview. One thing that one has to know is multiple access.

multipluxer multiplex the signals into one signal
a multiplexer (in short MUX) is a device which connects one of the n inputs to a single output lines so that the logical value of input is transferred to the output.
Instead of adding more wiring and more connections that may pose a reliability issue and increase the cost, we can use multiplexers to send data to many devices over fewer wir…es.
When the application layer passes large amounts of data to the transport layer. The transport layer multiplex different applications' communication by dividing the application… data into segments and placing a header on each segment to indicate which communication it is associated. Also, because networks can provide multiple routes that can have different transmission times, data can arrive in the wrong order. However by numbering and sequencing the segments, the transport layer can ensure that these segments are reassembled into proper order. Without segmentation, only one application would be able to receive data.

frequency division multiplexing and time division division multiplexing
In physical science, a electronic device may be a device that selects one in every of many analog or digital input signals and forwards the chosen input into one line. A e…lectronic device of 2 or N number inputs has n choose lines, that ar wont to choose that input line to send to the output. Multiplexers ar principally wont to increase quantity of knowledge that may be sent over the network among an explicit amount of your time and information measure. In fiber optic networking, a multiplexer contains many types such as CWDM multiplexer, DWDM multiplexer and Video multiplexer / Audio multiplexer / Data multiplexer, etc.. (all these multiplexers can be found in FiberStore with pictures)

In electronics, telecommunications and computer networks, multiplexing (short muxing) is a term used to refer to a process where multiple analog message signals or digital dat…a streams are combined into one signal over a shared medium. The aim is to share an expensive resource. For example, in electronics, multiplexing allows several analog signals to be processed by one analog-to-digital converter (ADC), and in telecommunications, several phone calls may be transferred using one wire. In communications, the multiplexed signal is transmitted over a communication channel, which may be a physical transmission medium. The multiplexing divides the capacity of the low-level communication channel into several higher-level logical channels, one for each message signal or data stream to be transferred. A reverse process, known as demultiplexing, can extract the original channels on the receiver side. Multiplexing technique is designed to reduce the number of electrical connections or leads in the display matrix. Whereas driving signals are applied not to each pixel (picture element) individually but to a group of rows and columns at a time. Besides reducing the number of individually independent interconnections, multiplexing also simplifies the drive electronics, reduces the cost and provides direct interface with the microprocessors. There are limitations in multiplexing due to complex electro-optical response of the liquid crystal cell. However, fairly reasonable level of multiplexing can be achieved by properly choosing the multiplexing scheme, liquid crystal mixture and cell designing.
application of multiplexing in data communication
What is the difference between an upward multiplexing and down-ward multiplexing When they are needed?
If only one network address is available on a host, all transport connections on that machine have to use it. When a TPDU comes in, some way is needed to tell which process to… give it to. This situation, called upward multiplexing. While if a user needs more bandwidth than one virtual circuit can provide, a way out is to open multiple network connections and distribute the traffic among them on a round-robin basis. This modus operandi is called downward multiplexing.

The range of frequencies is limited, but the number of devices using the system fluctuates. One way to separate the different data streams is each one have it's own frequency …(like different radio or TV stations broadcasting). This works fine when there are a limited number of users. Radio and TV are one-way, so there are a limited number of stations broadcasting. But with cell phones, broadband wireless and other services, the frequency spectrum is crowded. To have multiple users share the same frequency without walking over each other, multiplexing is used so that each user gets its data transmitted in packets. There are various methods of multiplexing available.

An encoder refers to a device that is used to change a signal or data into a code. Whereas a Multiplexer or mux is a device which performs multiplexing or it takes information… from more than one channels and outputs into a single channel. Thus a multiplexer is basically a kind of encoder where its function is to combine multiple inputs into one output.
A multiplexer is a device which can interweave two or more activities. So what it does exactly is it supports several input signals (analog or digital) and forwards that input… into a single line. Which means it makes it possible for several signals to share one device instead of having one device for each signal. One example is the multiplexer in a home stereo system that allows the user to choose audio from either CD, DVD or TV.
