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.

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)
Multiplexes are a bundle of TV services that has been compressed into a data stream. These are combined data in a single channel.
A multiplexer is an electronic device that sends several analog or digital input signals into one single line. This electronic is typically used in telecommunications.
Multiplexing is the ability of a number of devices to share a transmission facility.If each device needs the facility only a fraction of time,then the sharing arrangement allo…ws the cost of the facility to be spread over many users. post by Mohammed Alkhattab quote from William Stallings book
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.
cost saving by connecting a mux and demux together over a single channel.

An electronics multiplexer will select an output by a digital code. a mechanical multiplexer will select an out by a mechanical switch of sort possibly driven by a motor…

Doing more than one task at the same time. Such as watching the news and eating breakfast. In computer terms it means running multiple programs at the same time either by usin…g a multiple cored CPU, or by using a program switches CPU tasks based on clock cycles. In an OS these are referred to as processes. A quick check of my system shows that there are 57 processes running right now.
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.
The multiplexer collected data from the terminal and sent it to the distant end, with the address of the receiving terminal minimizing idle times between transactions
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.
Multiplexing is used to condense information. For instance, if you had four different telephone lines with their own numbers in a building but only had one pair of telephone… wires to the building, you could connect all four telephones to a multiplexer and connect the multiplexer to the single line coming into the building. On the other end of the single telephone line (at the phone switching station, for instance) you would connect a demultiplexer which would decode the information and send it to four individual phone lines. Furthermore, any or all four lines could be used at the same time without bothering the other lines.

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.
