Obviously we can use the expression (X ⊕ Y) for both calculations in the logic diagram. Now we have the final full adder circuit design. As nice as this design appears, it is not practical as an ...

[Aliaksei] starts with the basic building blocks of logic circuits, the AND and OR gates ... pistons that raise a flag when pressurized. The adder looks complicated, but it really is just a ...

making it feasible to construct any type of complicated logic IC reliably. In addition, more complex functional units such as a full adder, and MUX and DEMUX circuits are successfully demonstrated ...
