Answer Notes
In digital electronics, a truth table is a mathematical table used to completely describe the logical operation of a digital device, circuit, or gate. It methodically lists all possible combinations of input states (0s and 1s).
Next to every possible input combination, the table provides the corresponding output state produced by the device. This provides a clear, exhaustive map of how the logic circuit behaves under any condition.
Truth tables apply strictly to digital logic (discrete 1s and 0s). Distractors mentioning operational amplifiers (op-amps) are incorrect because op-amps are fundamentally analog devices that deal with continuous voltage ranges, not binary logic states.
