A digital climate control system uses a logic circuit to determine when to activate an auxiliary fan. The circuit has three inputs: AAA (temperature limit status), BBB (humidity limit status), and CCC (manual override status), and a single output QQQ (fan activation signal).
Write a Boolean expression to show how the output Q Q\,Q is calculated from the inputs AAA, BBB, and CCC.
You can use either the Boolean operator words (AND, OR, NOT) or their standard logic symbols.
