For two inputs A and B and output Y, the Boolean expression for NOR gate is

Options

  1. AY = A B
  2. BY = A B
  3. CY = A + B
  4. DY = A + B

Correct answer

C. Y = A + B

Step-by-step solution

A NOR gate is a combination of an OR gate followed by a NOT gate. The Boolean expression for an OR gate with inputs A and B is Y' = A + B . Passing this output through a NOT gate gives the final output Y = Y' . Therefore, the Boolean expression for a NOR gate is Y = A + B . Answer: Y = A + B
