Differbetween
Definition of Decoder and Demultiplexer– The key difference between a decoder and a Demultiplexer is that the former is a logic circuit that decrypts an encoded bit stream from one format into another, while the latter is a combination circuit that routes a single input line to multiple digital output lines.

What is difference between decoder and encoder?
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. In case of encoder, the applied signal is the active signal input. Decoder accepts coded binary data as its input.
What is the difference between a multiplexer and a demultiplexer?
A multiplexer is a combinational circuit that provides single output but accepts multiple data inputs. A demultiplexer is a combinational circuit that takes single input but that input can be directed through multiple outputs. ... It is N to 1 device and thus behaves as data selector.
Can a decoder be used as a demultiplexer?
A decoder with an enable input can function as a Demultiplexer. A demultiplexer is a circuit that receives information on a single line and transmits this information on one of 2n possible output lines.
What is the role of multiplexer and decoder?
A multiplexer and a decoder can be used together to allow sharing of a data transmission line by a number of signals. In the following diagram, the Control input consists of n wires, and there are 2n data inputs and outputs. The Control input determines which of the data inputs is connected to the transmission line.
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.
Why do we use decoder?
The decoder is an electronic device that is used to convert digital signal to an analogue signal. It allows single input line and produces multiple output lines. The decoders are used in many communication projects that are used to communicate between two devices.
Where is demultiplexer used?
Demultiplexer are also used for reconstruction of parallel data and ALU circuits. Communication System – Communication system use multiplexer to carry multiple data like audio, video and other form of data using a single line for transmission.
What are the 7 logic gates?
The basic logic gates are classified into seven types: AND gate, OR gate, XOR gate, NAND gate, NOR gate, XNOR gate, and NOT gate. The truth table is used to show the logic gate function. All the logic gates have two inputs except the NOT gate, which has only one input.
What is Demultiplex?
Demultiplex (DEMUX) is the reverse of the multiplex (MUX) process – combining multiple unrelated analog or digital signal streams into one signal over a single shared medium, such as a single conductor of copper wire or fiber optic cable.
Why Enable is used in decoder?
Apart from the Input lines, a decoder may also have an Enable input line. possible output lines. input lines that the decoder gets and the one input line of demulitplexer is the Enable input of the Decoder. Making 1:4 demultiplexer using 2:4 Decoder with Enable input.
How many outputs are on a BCD decoder?
A BCD to decimal decoder has ten output bits. It accepts an input value consisting of a binary-coded decimal integer value and activates one specific, unique output for every input value in the range [0,9].
Can an encoder be a transducer?
A rotary encoder, also called a shaft encoder, is an electro-mechanical device that converts the angular position or motion of a shaft or axle to analog or digital output signals. ... The output of an absolute encoder indicates the current shaft position, making it an angle transducer.
