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 ...

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 ...

so useful in fact engineers gave it its own symbol too -- an OR gate with a smile :) But most importantly, we can now put XOR into our metaphorical toolbox and not have to worry about the ...

There usually follows a demonstration of simple AND, OR, and XOR gates made from NAND gates ... part of your electronics general knowledge. Not [Alexander Shabarshin] though.
