- a similar table showing relationships between input to and output from a computer circuit
A table listing the truth-values of a proposition that result from all the possible combinations of the truth-values of its components.
(plural truth tables)
- (logic) a table showing all possible truth-values for an expression, derived from the truth-values of its components
- Each row of a truth table corresponds to a distinct interpretation. The columns on the left side assign truth values to the letters (of the truth table's given formula), and the column on the right side shows the truth value for the entire formula, which computably depends on the truth values of its letters.
