Multiplexer and De multiplexer in digital electronics/ Problems
Multiplexer is also called a Data selector
It has Multiple Input and Single Output
2^n input lines for n selection lines
Multiplexer selects one of the input data based on the Selection Signal (Sel)
De-multiplexer is a combinational circuit that receives information on a single line and transmits to one of the output lines
A decoder with enable input can function as a Demultiplexer.
Decoder converts binary information from n input lines to a maximum of 2n unique output lines. Only one output will be active at any time.
Multiplexers and Demultiplexers are combinational circuits
Combinational circuit - for different input combinations, we will get the output. The output at any time depends only on the input at that time.
No memory is required.
In this video you will learn how to design a multiplexer and demultiplexer and the difference between them.
