As an example, let’s consider the AND gate (the others are OR, NOT, NAND, NOR, XOR and XNOR). Electronic gates operate on two nominal voltages, normally 0 V and 5 V, representing the logic 0 ...

There usually follows a demonstration of simple AND, OR, and XOR gates made from NAND gates, and maybe a flip-flop or two. Then you move on, when you want a logic function you use the relevant ...

These DNA robots emulate a logical AND gate. Other DNA robots and systems of robots emulated OR, XOR, NAND, NOT, CNOT, and a half adder. This was described in 2014 but this article provides the 2014 ...

Why? I will explain, but first let me say to those who have been playing with this puzzle: (a) You can not use XOR gates and (b) there really is a solution. In fact, as “The Black Adder” would say ...

NAND gates are significant because any Boolean function (AND, OR, NOT, XOR, XNOR), which play a basic role in the design of computer chips, can be implemented by using a combination of NAND gates.

It is worth noting that 3XOR logic gates are not manufactured by the industry. It will be shown below how 2XOR and 3XOR elements can be synthesized from a set of standard discrete elements. Figure 1 ...
