Schematic of a 1-to-2 demultiplexer. Like a multiplexer, it can be equated to a controlled switch. In electronics, a multiplexer (or mux; spelled sometimes as multiplexor), also known as a data selector, is a device that selects between several analog or digital input signals and forwards the selected input to a single output line. [1]
Multiple low data rate signals are multiplexed over a single high-data-rate link, then demultiplexed at the other end.. In telecommunications and computer networking, multiplexing (sometimes contracted to muxing) is a method by which multiple analog or digital signals are combined into one signal over a shared medium.
A WDM system uses a multiplexer at the transmitter to join the several signals together and a demultiplexer at the receiver to split them apart. [1] With the right type of fiber, it is possible to have a device that does both simultaneously and can function as an optical add-drop multiplexer .
The carry-select adder generally consists of ripple-carry adders and a multiplexer.Adding two n-bit numbers with a carry-select adder is done with two adders (therefore two ripple-carry adders), in order to perform the calculation twice, one time with the assumption of the carry-in being zero and the other assuming it will be one.
In optical communication, a reconfigurable optical add-drop multiplexer (ROADM) is a form of optical add-drop multiplexer that adds the ability to remotely switch traffic from a wavelength-division multiplexing (WDM) system at the wavelength layer. This is achieved through the use of a wavelength selective switching module.
An example table rendered in a web browser using HTML. A table is an arrangement of information or data, typically in rows and columns, or possibly in a more complex structure. Tables are widely used in communication, research, and data analysis. Tables appear in print media, handwritten notes, computer software, architectural ornamentation ...
Digroup is an abbreviation for digital group. In telephony, a basic group in the digital multiplex hierarchy.. In the North American and Japanese T-carrier digital hierarchies, each digroup supports 12 PCM voice channels or their equivalent in other services.
Diplexing is used to prevent intermodulation and keep reflected power to a minimum for each input transmitter and frequency.While diplexers can combine a relatively wide bandwidth, the major limitation comes with the antenna itself, which must be sufficiently wideband to accept all of the signals being passed through it, and transfer them to the air efficiently.
