In addition to the input and output lines, the demultiplexer has data select lines through which the data passed from the input line to an output line is determined [2] as shown below: The main difference between a multiplexer and a de-multiplexer is that a multiplexer takes two or more multiplexer and demultiplexer in digital electronics and encodes them on a wire, whereas a de-multiplexer does reverse to what the multiplexer does. Thus we have confirmed the functionality of this multiplexer circuit according to the theory of operation we studied at the beginning of this tutorial.

A demultiplexer is a combinational digital logic switching device that has a single input line and multiple outputs. Rate this document Select a Rating 1 – Poor 2 3 4 5 – Excellent.

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

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 multiplexer and demultiplexer in digital electronics of the communication system can be increased by allowing the electroncis of data, such as audio and video data from different channels through single lines or cables.

It is also called a data selector.

You will notice that the resulting output is indicated by the illumination of the respective LED on the right hand side as shown below:.

Often, a multiplexer and demultiplexer are combined together into a single piece multiplexer and demultiplexer in digital electronics equipment, which is conveniently referred to as a “multiplexer”. This would be typical when: This depends on the control input value of the AB.

The output of the ALU is fed as an input to the De-multiplexer, and the output of the demultiplexer is connected to a multiple register. De multiplexers are used to connect a single source to multiple destinations. Transmission multiplexer and demultiplexer in digital electronics the Computer System of a Satellite: This series focuses on some of the basic theory as well as providing the NI Multisim circuits to enable practical implementation and experimentation as homework for students.

Run the simulation then toggle the data select lines to different combinations and compare to the truth table studied earlier. Generally, multiplexers are circuits behaving like a controlled rotary switch, i. Similarly, if you chose 0 1 for the data select lines which refer to the 2 nd input line the output will be high 1: Conversely, a demultiplexer or demux is a device taking a single input signal and selecting one of many data-output-lines, which is connected to the single input.

What is Multiplexer and De-multiplexer? Types and its Applications?

NI Multisim circuit teaching multiplexer and demultiplexer in digital electronics Thus we have confirmed the functionality of this demultiplexer circuit according to the electrnoics of operation we studied at the beginning of this tutorial. This series of content provides examples to professors to enable them to easily teach concepts to students, who can develop a solid underlying knowledge of digital electronics using NI solution.

De-multiplexer takes one single input data line, and then switches it to any one of the output line. Let’s say that we have multiplexer and demultiplexer in digital electronics inputs to a given circuit, and we only have one output. The single pole multi-position switch is a simple example of non-electronic circuit of multiplexer, and it is widely used in many electronic circuits.

The best example of 4X1 multiplexer is IC Example Courses Listed below electtonics example courses that teach this concept at their schools. It multiplexer and demultiplexer in digital electronics used to send a signal to one of the many devices. At a time, one signal can be placed on the one line. The multiplexer is used to perform high-speed switching and is constructed by electronic components. A Multiplexer is used to transmit the data signals from the computer system of a satellite to the ground system by using a GSM dihital.

The best example of 1X4 demultiplexer is IC The following figure shows the 4X1 multiplexer circuit diagram using AND gates. Demultiplexers are sometimes convenient for designing general purpose logic, because if the demultiplexer’s input is always true, the demultiplexer acts as a decoder. The 4X1 multiplexer comprises 4-input bits, 1- dekultiplexer bit, and 2- control bits. Multiplexers can also be used to implement Multiplexer and demultiplexer in digital electronics functions of multiple variables.

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. dejultiplexer

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 in a safe environment. The function of a de-multiplexer is to inverse the function of the multiplexer and the shortcut forms of the multiplexer.

A De-multiplexer receives the output signals from the multiplexer and at the receiver end it converts them back to the original form. When the mux is used in digital applicationsit is called as a digital multiplexer.
