Revise: Truth Table InterpretationFor the row where A = 0 and B = 1, AND produces 0, while OR and XOR both produce 1. This tells you what each operation does for that particular combination.
Exclusive OR: a logical operation that produces 1 when exactly one of two inputs is 1. Written using a circled plus: .
OR includes the case where both inputs are 1; XOR does not.
Use the required notation: . for AND, + for OR, ⊕ for XOR and an overbar for NOT.
Check the case where both inputs are 1: OR gives 1, but XOR gives 0.
