What is a multiplexer logic circuit?
The multiplexer, shortened to “MUX” or “MPX”, is a combinational logic circuit designed to switch one of several input lines through to a single common output line by the application of a control signal. The most basic type of multiplexer device is that of a one-way rotary switch as shown.
Can a multiplexer be used to realize a logic function?
The main function of a multiplexer is to route only one selected data input to its single output. Because of its unique structure, a multiplexer can also be used to implement a logic function.
What are multiplexers used for?
A multiplexer is a device that takes multiple analog signals and forwards the selected input into a single line. These devices are used to increase the amount of data that can be transmitted over a network.
What is the advantage of using multiplexers to implement logic gates?
1] It reduces ckt complexity and cost. 2] We can implement many combinations logic ckts using multiplexer. 3] It does not need K-maps and simplification.
Is multiplexer a decoder?
Decoder is a logic circuit which n input lines into m output lines….Difference between of Multiplexer and Decoder :
| S.NO. | Multiplexer | Decoder |
|---|---|---|
| 1. | MUX accepts several inputs and allow only one data output. | It takes n input binary code and convert it into a corresponding outputs. |
How would you implement a function using multiplexers?
Implementation of SOP function using multiplexer
- Step 1: Draw the truth table for the given number of variable function.
- Step 2: Consider one variable as input and remaining variables as select lines.
- Step 3: Form a matrix where input lines of MUX are columns and input variable and its compliment are rows.
What advantages do multiplexers have for electronic systems?
Advantages of Multiplexer 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, analogue signals etc.
What is multiplexer and its importance?
Multiplexers, often called muxes, are extremely important to telecommunications. Their main reason for being is to reduce network costs by minimizing the number of communications links needed between two points. As with all other computing systems, multiplexers have evolved.
How are multiplexers used in digital logic circuit?
Multiplexers in Digital Logic. It is a combinational circuit which have many data inputs and single output depending on control or select inputs. For N input lines, log n (base2) selection lines, or we can say that for 2 n input lines, n selection lines are required.
What’s the difference between a multiplexer and a concentrator?
This page on Concentrator vs Multiplexer describes difference between Concentrator and Multiplexer . A multiplexer is a combination circuit which will have more than one input lines, selection lines and one output line. It selects one input line and directs the data to the output line.
How is the output of a multiplexer controlled?
For example, a single 8-channel multiplexer. Generally, the selection of each input line in a multiplexer is controlled by an additional set of inputs called control lines and according to the binary condition of these control inputs, either “HIGH” or “LOW” the appropriate data input is connected directly to the output.
Which is an advantage of using a multiplexer?
The advantage is that only one serial data line is required instead of multiple parallel data lines. Therefore, multiplexers are sometimes referred to as “data selectors”, as they select the data to the line.
