It either shows True and False values or 0 and 1 values. Now, if you want to calculate truth tables for Boolean expressions, propositional formulae, and logic circuits, you can refer to this post.

Like [Brad], we’ve seen a number of PCB rulers out there. [Brad] was looking to take the idea and run with it. His DigiRule is a ruler with a logic gate simulator. What he built is a mash-up … ...

This can be seen in the truth table below. If input A is true then output Q is NOT true, if input A is false then output Q will NOT be false (i.e., true). The Boolean expression is Q = NOT A.

Truth diagrams (TDs) are introduced as a novel graphical representation for propositional logic (PL). To demonstrate their epistemic efficacy a set of 28 concepts are proposed that any comprehensive ...
