Answer:
A demultiplexer (DEMUX) is a digital circuit that routes a single input line to one of several output lines. It can be implemented using OR gates.
Here's one way to make a 2-to-4 demultiplexer using OR gates:
Begin by connecting the input line to the input of the first OR gate.
Connect one of the select lines to the second input of the first OR gate.
Connect the output of the first OR gate to one of the outputs.
Connect the second select line to the second input of the second OR gate.
Connect the output of the first OR gate to one input of the second OR gate.
Connect the output of the second OR gate to the second output.
Repeat steps 4-6 for the remaining outputs.
By this way you can construct a demultiplexer using OR gates.
It's important to note that the number of select lines must be equal to the number of bits required to select the output. In this example, we used 2 select lines to control the 4 outputs, so we only needed 2 bits to select the output.
