The main function of the multiplexer is that it combines input signals, allows data compression, and shares a single transmission channel.

This article gives an overview of multiplexer and demultiplexer. You can help to develop the workor you can ask for assistance in the project room.

They forward the data input to one of the outputs depending on multiplexer and demultiplexer in digital electronics values of the selection inputs. Learn more about our privacy policy. In electronicsa multiplexer or mux is a device that selects one of several analog or digital input signals and forwards the selected input into a single line.

Digital Design and Computer Architecture. Hi, Thanks for your compliment And once again please visit our domestic website http: Furthermore, any doubts regarding digitsl article or electronics projectsYou can write your views about this topic in the comment section below.

Back to Top 6. This converter is used multiplexer and demultiplexer in digital electronics reconstruct parallel data. Run the simulation then toggle muliplexer data select lines to different combinations and compare to the truth table studied earlier. Save my name, email, and website in this browser for the next time I comment. Let’s say that we have 2 inputs to a given circuit, and we only have one output.

The multiplexer is used to perform high-speed switching and is constructed by electronic components. The best example of 4X1 multiplexer is IC Example Courses Listed below are example courses that teach this concept at their schools.

The series has several ICs that contain demultiplexer s:. Demultiplexers are used to connect a single source to multiple destinations.

Operations of Multiplexer and De-multiplexer Circuit and Applications

The input bit is considered as data D and it is transmitted to the output lines. We are a group of volunteers and starting a new project in a community in the same niche. Similar to the situation above, let’s say we have a circuit with a single input Itwo multiplexer and demultiplexer in digital electronics O1 and O2and a control wire, C. Then we examine two example circuits which can be used by any educator or student to verify our results using NI Multisim.

A De-multiplexer receives the output signals from the multiplexer and demultiplexer in digital electronics and, at the receiver end, it converts them back to the original form. As an input, the combination of selection inputs are giving to the AND gate with the corresponding input data lines. By using a multiplexer, the vemultiplexer of the elextronics system can be increased by allowing the transmission of data, such as audio and video data from different channels through single lines or cables.

For telecommunications, see multiplexing. The following 4-to-1 multiplexer is constructed from 3-state buffers and AND gates the AND gates are acting as the decoder:. In analog circuit design, a multiplexer is a special type of analog switch that connects demultlplexer signal selected from several inputs to a single output. So the value of the F1 depends on the value of D, and the remaining outputs are in low state.

When the multiplexer is used for digital applications, multiplexer and demultiplexer in digital electronics is called a digital multiplexer. Multiplexer is used to transmit the data signals from the computer demultiplexef of a spacecraft or a satellite to the ground system by using a GSM satellite. In some cases, the far end system may have functionality greater than a simple demultiplexer; and while the demultiplexing still occurs technically, it may never be implemented discretely.

You will notice that the resulting output is indicated by the illumination of the respective Demultiplxeer on the right hand side as shown below:. The 1-to-4 demultiplexer comprises 1- input bit, 4-output bits and — control bits. De-multiplexer is also a device with one input and multiple output lines.

We would like the two inputs multiplexer and demultiplexer in digital electronics “share” the output, electronicw we therefore need to switch from one input to the other.

For furthermore details please contact to Mr. The 4X1 multiplexer comprises 4-input bits, 1- output bit, and 2- control bits. You will find the circuit below:. It is used to send a signal to one of the many devices.

The Digital Electronics Basics series present the multiplexer and demultiplexer in digital electronics theories and concepts taught at entry level electronics courses at both 2 year and 4 year institutions. Combining an intuitive circuit definition environment, with powerful SPICE simulation technology, educators can use NI Multisim to easily teach the ins-and-outs of circuits multiplexer and demultiplexer in digital electronics a safe environment.

In addition to the input and output lines, the multiplexer has data select lines through which the data passed from an input line to the output line is determined [1] as shown below:.

A multiplexer is also called as a data selector. Demultiplexers are sometimes convenient for designing general purpose logic, because if the demultiplexer’s digial is always true, the demultiplexer acts as a decoder. In addition to the input and output lines, the demultiplexer has data select lines through multiplxeer the data passed from the input line to an output line is determined vemultiplexer as shown below:.

De multiplexers are used to connect a single source to multiple destinations. Single-core processor Multi-core processor Manycore processor.
