Each of the inputs and output(s) can attain either of two states: logic 0 (low) or logic 1 (high). A common example is a simple logic gate . WebTruth-functional form So we have seen that some logical truths are tautologies, and some are not. To be able to decide whether an FOL sentence that contains quantifiers is a tautology, we need to develop the notion of a sentence’s truth-functional form.
