The McCluskey Algorithm is a method used in digital logic design to simplify boolean functions. It systematically reduces complex expressions into simpler forms, making it easier to implement in electronic circuits. The algorithm works by identifying and combining minterms, which are the simplest forms of boolean expressions. This algorithm is particularly useful for minimizing the number of logic gates needed in a circuit. By creating a truth table and grouping minterms, the McCluskey Algorithm helps designers find the most efficient way to represent a boolean function, ultimately leading to cost-effective and reliable circuit designs.
