What term describes the set of output values for all possible input combinations of a logic circuit?

• A. Truth Table
• B. Function Table
• C. Karnaugh Map
• D. Boolean Algebra

Answer: (B)

In digital logic, describing how a circuit behaves for every possible input uses a truth table. It lists each input combination and the corresponding output values, so together they show the complete input-output behavior. If you have n inputs, you’ll see 2^n rows, one for each input pattern, with the circuit’s outputs in the same row. This table is the standard reference you’d use to understand or analyze the circuit, and it’s the starting point for simplification methods like Karnaugh maps or algebraic manipulations in Boolean algebra. A Karnaugh map is simply a graphical way to visualize and minimize the same function, built from the truth table. Boolean algebra provides rules to transform the expressions, but doesn’t itself present the full input-output mapping in one place. The term “function table” isn’t typically used to describe the complete set of outputs for all input combinations.
