For the students of 12th standard electronics and engineering here is the simple explanation of working of 1:4 Line Demultiplexer using Basic Gates. This circuit simulation will give you a very clear idea about the working of 1:4 line demux using basic gates.
We know that the Demux is called as data distributor circuit because it can distribute a single data input over number of its available outputs.
For more details refer our Digital Electronics Book written by Vidyasagar Sir, for the students of applied electronics of 12th standard. This book is also useful for polytechnic and engineering students.
