What is Demultiplexer?
The decoder is a combinational circuit that has 1 input and M outputs and depending on the inputs at the selection lines, the input of the demultiplexer appears at one of the outputs. That's why it is also called, one to many device.
If the multiplexer has N selection lines then total 2 ^ N outputs can be distinguished using the N selection lines.
Depending on the number of selection lines and outputs, there are different types of Demultiplexers.
e.g 1 to 2 Demultiplexer, 1 to 4 Demultiplexer, 1 to 8 Demultiplexer etc.
Applications of Demultiplexer:
In time-division multiplexing applications, the multiplexer and demultiplexer are used together. The multiplexer is used on the transmitter side, while the demultiplexer is used on the receiver side.
It can also be used for Serial to Parallel Conversion.
And since the design of Demultiplexer is similar to the Decoder, it can also be used in all the applications where the decoder is used.
The Decoder as Demultiplexer:
In this video, how to use the decoder as a demultiplexer is explained. And at the later part of the video, using the Demultiplexer, how to implement the different Boolean Functions is also explained.
This video will be helpful to all the students of science and engineering in understanding what is demultiplexer, its applications, and how to use demultiplexer for implementing different logic circuits.
