The NOR gate is logically equivalent to an OR gate followed by an _____ A. AND B. XAND C. XOR D. inverter E. None of the above

The correct answer

A NOR gate is a logic gate that implements logical NOR, that is, the negation of the OR function. It behaves like an OR gate followed by an inverter.

An OR gate is a logic gate that implements logical OR, that is, the function that produces a true output if either or both of its inputs are true.

An inverter is a logic gate that inverts its input, producing a true output if its input is false, and a false output if its input is true.

Therefore, a NOR gate is logically equivalent to an OR gate followed by an inverter.
