The multiplexer acts like an electronic switch that selects one from. As with the previous multiplexer circuit, adding more address line inputs it is possible to switch. The demultiplexer is a combinational logic circuit that performs the. Multiplexer mux and multiplexing tutorial electronicstutorials. The action or operation of a demultiplexer is opposite to that of the multiplexer. An simple example of an non electronic circuit of a multiplexer is a single pole. For analog application, multiplexer are built of relays and transistor switches. Again the output line is selected using an address. Multiplexer can act as universal combinational circuit. A digital circuit that directs one of several inputs to a single output based on the state of several select inputs. Multiplexing is the generic term used to describe the operation of sending one or more analogue or digital signals over a common transmission line at different times or speeds and as such, the device we use to do just that is called a multiplexer the multiplexer, shortened to mux or mpx, is a combinational logic circuit designed to switch one of several input lines through to a. The implementation of not gate is done using n selection lines.

Electronics tutorial about the multiplexer mux and digital multiplexers used in combinational logic circuits for the multiplexing of data signals. Electronics tutorial about the demultiplexer demux used for data distribution in combinational logic circuits including digital decoders. Multiplexer handle two type of data that is analog and digital. For digital application, they are built from standard logic gates. In analog applications, multiplexers are made up of of. The multiplexer is used to perform highspeed switching and is constructed by electronic components multiplexers are capable of handling both analog and digital applications. Multiplexer and demultiplexer is a combinational of digital logic switching device. Digital circuits multiplexers multiplexer is a combinational circuit that has maximum of 2n data inputs, a. One of these data inputs will be connected to the output based on the values of selection lines.

A general overview of multiplexer and demultiplexer. The multiplexer used for digital applications, also called digital multiplexer, is a circuit with many input but only one output. Dwdm mux demux, fiber optic multiplexer demultiplexer fs. Multiplexing and demultiplexing logic functions for computing. Fs passive dwdm mux demux 496 channels greatly saves optical fiber resources for longhaul, scalable otn networks by dense wavelength division multiplexing tech. Lecture notes for digital electronics university of oregon. A muxdemux pair can be used to convert data to serial form for transmission, thus reducing the number of. Arduino uno projects for beginners and engineering students. The demultiplexer converts a serial data signal at the input to a parallel data at its output. All the standard logic gates can be implemented with multiplexers. By setting the input to true, the demux behaves as a decoder. Multiplexer is a combinational circuit that has maximum of 2 n data inputs, n selection lines and single output line. Demultiplexer demux digital decoder tutorial electronics. Mux is often used with a complementary demux on the receiving end.

The data distributor, known more commonly as a demultiplexer or demux for short, is the exact opposite of the multiplexer we saw in the previous tutorial the demultiplexer takes one single input data line and then switches it to any one of a number of individual output lines one at a time. As inverse to the mux, demux is a onetomany circuit. The single pole multiposition switch is a simple example of nonelectronic circuit of multiplexer, and it is widely used in many electronic circuits.
