Logically, the output of a NOR gate would have the same Boolean expression as a(n):

  • A.NAND gate immediately followed by an inverter
  • B.OR gate immediately followed by an inverter
  • C.AND gate immediately followed by an inverter
  • D.NOR gate immediately followed by an inverter

Answer: B

Correct answer: OR gate immediately followed by an inverter

NOR means NOT-OR: \( (A+B)' \). Inverting the output of an OR gate produces exactly that expression.
