What is the difference between Decoder and Demultiplexer?

The difference between demultiplexer and decoder is that decoder is a combinational circuit that accepts numerous inputs to generate decoded output while the demultiplexer is a combinational circuit that accepts one input and directs it into one of the several outputs.

A decoder translates coded digital inputs signals into output signals while a demultiplexer consolidates data streams into single information. A demultiplexer transmits data from one line to 2 possible output lines while the decoder takes in n lines and produces 2 output lines.

A decoder has no selection line while a demultiplexer output line is determined by the value of the selected line. A decoder is used in the user interface in output devices like calculators, DVD players, Printers, and many more. The input binary code for a decoder is 2, 3- or 4-bit code.

With the definition of decoder and demultiplexer, you will be able to understand some of the differences between the two. A decoder is a device used to convert an encoded bit stream, mostly from one format to another. If you understand the term encoding, it will be very easy for you to understand what a decoder is because the latter is just a reverse of what the former does. With a decoder, encoded data can be easily converted into different kinds of signals.

On the other hand, a demultiplexer is also a device that helps connect a single input line to different output lines, especially digital ones. While a decoder reverses the functions of an encoder, a demultiplexer also reverses the functions of a multiplexer.

While there are 1-16 demultiplexers, 1-8 demultiplexers, and 1-4 demultiplexers, decoders are usually grouped as 4-to-16 decoders, 3-to-8 decoders, and 2-to-4 decoders. However, both devices are used in communication systems.

Decoders are logic circuits. They decrypt a bitstream that has been encoded. This decryption transforms from one format into another. Demultiplexers are combination circuits. Their function is to move an input line from one to multiple ones. Decoders are the opposite of encoders.

Demultiplexers are the opposite of multiplexers. Both are used in a number of different types of products related to the field of technology. Decoders are used in systems like wireless communication and memory address decoding.

Demultiplexers are popular in telecommunication systems. There are many types of both. For instance, decoders can have 2-4 or 4-16 decoders. Demultiplexers can have 1-4 or 1-16.

A decoder is a combinational rationality circuit that converts code into a set of signals. It is used in the user interface in most of the output devices, such as calculations, monitors, printers, and DVD players. It possesses multiple inputs and outputs and is used to transfer coded inputs into coded outputs.

A demultiplexer is a blended logic circuit that takes one output line and routes it to numerous output lines. They are used to execute general-purpose logic. A demultiplexer is used when a circuit attempts to transmit a signal to one of many devices. It does precisely the opposite of what a multiplexor does, while a decoder is the inverse function of an encoder.
