Which term would you use to express a logic function using algebraic-like notation?

• A. Logic expression
• B. Truth table
• C. High-level language
• D. Logic circuit

Answer: (A)

Expressing a logic function in an algebraic-like form uses symbols for variables and logical operators to build a compact formula. This is exactly what a logic expression does: it combines variables with operators such as AND, OR, and NOT to describe the output for any given input. For example, a function written as F = (A AND NOT B) OR C is an algebraic-like expression that encodes the logic. A truth table, on the other hand, lists input combinations and outputs without a symbolic formula. A high-level language is for writing software, not for expressing logic functions in symbolic form. A logic circuit represents the function as hardware or a schematic, not as a symbolic expression. So the best term is a logic expression.
