- D.
An OR gate without inversion
Attempted by 274 students.
Show answer & explanation
Correct answer: C
For a NOR gate, the output is Y = (A + B)'. By De Morgan's theorem, (A + B)' = A'B'. This means a NOR gate can be represented as an AND gate with both inputs inverted. Therefore, the correct equivalent is an AND gate with inverted inputs.
