Question

When the output of an OR gate is supplied to a NOT gate, the combination is equivalent to which gate?

G1 Physics · Accepted Answer

An OR gate produces A + B. Passing its output into NOT produces Y = NOT(A + B) = (A + B)̅. This is the defining Boolean relation for a NOR gate. Final answer: Option B.
