What is a demultiplexer?

Demultiplexer or "Demux" is a piece of equipment that takes one signal carrying more pay -up loads and divides it into several streams. They are often used in telecommunications to carry signals over long distances. The demultiplexer is the opposite of the multiplexer. Multiplexer or "Mux" takes signals from many sources and puts them in a single signal. This signal is transmitted wherever you need to go, and then dismantled by a demultiplexer at the other end. It is the only device with many small buckets that collect water in each of them. The water is then transported and then dropped by each separate bucket. Water intake during multiplexing and release on the other side is demultiplexing. This is a way to get many pieces of operation from one place to another without having to have separate wires for everyone.Kets "are time plans. If someone calls from an office in New York, such as another office in New Jersey, the call is sent from the office to the local telephone exchange.K send him to New Jersey multiplexer.

Call is given time section, 36 in this example and sent on a journey through thread to New Jersey. Like the call data - the voice of the person - the more information is provided by a multiplexer that says to the other end, while the call takes place, everything that comes to Timeslot 36 is for this particular call. On the other hand, the demultiplexer raises information, sees that everything comes to Timeslot 36 is for the office in New Jersey, and sends them on the way through a telephone exchange.

This process of multiplexing and demultiplexing takes place hundreds of times for a second for each conversation that takes place at longer distances. If someone was to call all over the country, her conversation, still in Timeslot 36, he would be checked at every main exchange and sent on the road until she reached the city she called. This exchange would see that the call was for someone who was connected with him and "breaks" the call and demultipLex. The process is so refined and the device so quickly that although call data could be checked 20 or 30 times, the caller perceives no call delay.
