How to use Truth Table Generator
Type an expression with letters for variables. Optionally add a second expression to check whether both are equivalent, for example De Morgan’s laws.
How it works
Precedence: NOT, AND/NAND, XOR, OR/NOR, implication (right-associative), equivalence. Simplification uses the Quine–McCluskey method with a greedy cover; the result is always equivalent.
Example
(A AND B) OR NOT C is true in 5 of 8 rows, Σm(0, 2, 4, 6, 7), and simplifies to ¬C ∨ (A ∧ B).
