What are MUX demux encoders and decoders?
The digital circuits that perform encoding of digital information are called encoders while digital circuits that decode the coded digital information are called decoders. An encoder with enable pins is called multiplexer while a decoder with enable pins is called demultiplexer.

What is multiplexer and demultiplexer PDF?
Multiplexer and Demultiplexer. A multiplexer is a circuit that accept many input but give only one output. A demultiplexer function exactly in the reverse of a multiplexer, that is a demultiplexer accepts only one input and gives many outputs.
What is MUX and decoder?
Decoder. Definition. A combinational logic circuit which has 2n input lines and only 1 output lines is called multiplexer or MUX. A combinational logic circuit which has ‘n’ input lines and maximum 2n output lines is known as decoder.
What is encoder and decoder with diagram?
Encoder circuit basically converts the applied information signal into a coded digital bit stream. Decoder performs reverse operation and recovers the original information signal from the coded bits. 2. In case of encoder, the applied signal is the active signal input. Decoder accepts coded binary data as its input.
What are decoders used for?
The decoder is an electronic device that is used to convert a digital signal to an analog signal. It allows a single input line and produces multiple output lines. The decoders are used in many communication projects that are used to communicate between two devices.
What is a encoder?
An encoder is a sensor that detects rotation angle or linear displacement. Encoders are used in devices that need to operate in high speed and with high accuracy.
What is multiplexer PPT?
o A MULTIPLEXER is a digital circuit that has multiple inputs and a single output. o The selection of one of the n inputs is done by the select inputs o It has one output selected at a time. o It is also known as DATA SELECTOR.
What is a multiplexer PDF?
➢ A Multiplexers (MUX) is a combinational logic component that has several inputs and only one output. ➢ MUX directs one of the inputs to its output line by using a control bit word (selection line) to its select lines.
What are the types of decoder?
There are various types of decoders which are as follows:
- 2 to 4 line decoder: In the 2 to 4 line decoder, there is a total of three inputs, i.e., A0, and A1 and E and four outputs, i.e., Y0, Y1, Y2, and Y3.
- 3 to 8 line decoder: The 3 to 8 line decoder is also known as Binary to Octal Decoder.
- 4 to 16 line Decoder.
What is multiplexer with diagram?
The block diagram of 4×1 Multiplexer is shown in the following figure. One of these 4 inputs will be connected to the output based on the combination of inputs present at these two selection lines. Truth table of 4×1 Multiplexer is shown below.

Where is encoder used?
For our purposes, encoders are used in machinery for motion feedback and motion control. Encoders are found in machinery in all industries. You’ll find encoders used in cut-to-length applications, plotters, robotics, packaging, conveying, automation, sorting, filling, imaging, and many, many more.
What is encoder example?
An encoder is a combinational circuit that converts binary information in the form of a 2N input lines into N output lines, which represent N bit code for the input. For simple encoders, it is assumed that only one input line is active at a time. As an example, let’s consider Octal to Binary encoder.

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. A network multiplexer is used with a variety of signal types like digital, video, analog, and optical….
What is application of multiplexer?
Applications of Multiplexer
Multiplexer allow the process of transmitting different type of data such as audio, video at the same time using a single transmission line. Telephone Network – In telephone network, multiple audio signals are integrated on a single line for transmission with the help of multiplexers.
What is type of encoder?
An encoder is classified into four types: mechanical, optical, magnetic, and electromagnetic induction types. There are four types of information necessary to rotate the motor with high accuracy: rotation amount, rotational speed, rotational direction, and rotational position.
What is called encoder?
Simply put, an encoder is a sensing device that provides feedback. Encoders convert motion to an electrical signal that can be read by some type of control device in a motion control system, such as a counter or PLC. The encoder sends a feedback signal that can be used to determine position, count, speed, or direction.
What is the application of decoder?
The decoder is used as address decoders in CPU memory location identification. It is also be used in electronic circuits to convert instruction into CPU control signals. They are mainly used in logical circuits, data transfer.
What is the principle of multiplexer?
The process of multiplexing divides a communication channel into several number of logical channels, allotting each one for a different message signal or a data stream to be transferred. The device that does multiplexing, can be called as a MUX.
How many types of multiplexers are there?
There are three types of Multiplexing : Frequency Division Multiplexing (FDM) Time-Division Multiplexing (TDM) Wavelength Division Multiplexing (WDM)
What are advantages of multiplexers?
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. 4] On the advance level the ability of MUX to switch directed s/g can be extended to smter video.

What is decoder example?
A decoder is a combinational circuit which has many inputs and many outputs. It is used to convert binary data to other codes. Examples: binary to octal conversion using 3 to 8 decoder, BCD to decimal conversion using 4 to 10 decoder, binary to hexadecimal conversion using 4 to 16 decoder, etc.
What are the applications of Demux?
Applications of Demultiplexer (Demux)
Demultiplexer (Demux) and Multiplexer (MUX) both are used in communication systems to carry multiple data signals (i.e. audio, video etc) using single line for transmission.
Why is MUX used?
The purpose of multiplexing is to combine and transmit signals over a single shared medium in order to optimize efficiency and decrease the total cost of communication.
