Minimization of Boolean Functions - GeeksforGeeks
Example: Simplify the Boolean function F = AB + (AC)′ + AB′C (AB + C). Solution: F = AB + (AC)′ + AB′C (AB + C) = AB + A′ + C′+ AB′C.AB + AB′C.C. = AB + A′ + C′ + 0 + AB′C (B.B′ = 0 and C.C = C) = ABC + ABC′ + A′ + C′ + AB′C (AB = AB (C + C′) = ABC + ABC′) = AC (B + B′) + C′ (AB + 1) + A′. = AC + C′+A′ (B + B′ = 1 and AB + 1 = 1) = AC + (AC)′ = 1.
