Multiplexeris an electronic device , A multiplexer is a circuit that accept many input but give only one output . it is also known as Data Selector. multiplexer is combination of many logical Gates. It has ( multiplexer ) many several Analog or Digital Inputs but only one output. A multiplexer of 2^n inputs has select lines, which are used to select which input line to send to the output.In telecommunications the combined signals, analog or digital, are considered a single-output higher-speed signal transmitted on several communication channels by a particular multiplex method or technique . Mainly the multiplexer are use for increase amount of Data that can be sent over the network within in time and bandwidth.multiplexer are used to increase the efficiency of the communication system by allowing the transmission of data, such as audio & video data from different channels via cables and single lines.
ANALOG MULTIPLEXER:-
- "a multiplexer is a special type of analog switch that connects one signal selected from several inputs to a single output."
DIGITAL MULTIPLEXER:-
- "a multiplexer (or mux), also known as a data selector, is a device that selects between several analog or digital input signals and forwards it to a single output line. A multiplexer of inputs has select lines, which are used to select which input line to send to the output. "
Multiplexing (CWDM)
"Multiplexer can facilitate the transmission of data through a single line, this makes the transmission circuit economical and less complex. Besides, the ability of multiplexer to switch digital signals can be extended to switch video signal, analog signal. "
