It is a recent method for multiplexing signals comprised of multiple channels carried by electromagnetic signals over a unified way. In 100Gbit/s per channel, specification is used in fiber-optic networks. It is practically implemented in frequency modulation applications and optical communications. It polarizes the electromagnetic signals to segregate orthogonal channels. If it is done in an appropriate method, the receiving devices ill not diagnose that few of the circuit time that was utilized to the server the other logical communication path. So that it can be related to the correct receiver. It involves sequencing the group of few bits from every individual input spectrum continuously. It is a digital method which uses time instead of accuracy or space to segregate the variable data streams. A variant technology of this is used in optical communications called wavelength division multiplexing. The application of FDM is television broadcasting from remote sources, cable television, mobile or satellite divisions, and traditional radio. The frequency division multiplexing attains by merging numerous signals into a single signal in one medium by transmitting the signals in several frequencies ranges over a single medium. The spectrum of every input signal is moved to a distinct frequency range. In a multiple paired telephone wire, a switched star system such as a network for telephone access, mesh network and switched ethernet. It involves an analog stereo wire with a single couple of wires for left networks and others for a suitable network. The multiplexing based on space-division uses the distinct node to node electric conductors for every communicated channel. The multiplexing is attained by altering the horizontal and vertical polarization on each side of the channels or it passes through an array of multi-antenna along with scheme of multi-input and multi-output communications. The digital bitstreams can be transported over analog channels by code-division multiplex methods like FHSS as a frequency hopping speed spectrum and DSSS as a direct sequence spread spectrum. It is an asynchronous mode of multiplexing based on time division. Multiple variable bit rate digital bits are transported effectively over a unit bandwidth by using statistical multiplexing. Hadoop, Data Science, Statistics & others Types of Multiplexing Techniques So it has only single input and many outputs.
Demux splits the signal into its related or component signals. This process is made possible with de-multiplexer and it’s popularly known as DEMUX. The reversible process used for the extraction of a number of channels from a single signal, implemented at the end of multiplexer or receiver is known as de-multiplexing. If the analog signals are multiplexed it is called analog multiplexing and if the digital signals are multiplexed it is referred to as digital multiplexing. The process of converting many signals into one signal over a shared medium is called Multiplexing. The structure of the MUX has many input signals where its output is only one output signal. The overall process can be performed using d device, Multiplexer, popularly called as MUX.
It is also implemented to transport a link or medium with a number of specified devices. In a general method of the multiplex, it combines a finite number of low-speed signals to broadcast over a high-speed link. It is applicable in computer networks, telecommunication, telegraphy, telephony, and video broadcasting. The term multiplexing is defined as a transmission method to transport different multiple analogs and digital signals into a single signal over a network or a channel.
