(A) This is a NAND gate
(B) if A = 0, B = 0 then Y = 1
(C) if A = 0, B = 1 then Y = 0
(D) if A = 1, B = 0 then Y = 1
(E) if A = 1, B = 1 then Y = 1
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 3
This is a NOR GATE.
For NOR Gate output is 1 only if both X and Y is zero. In all other case Output will be 1.
Hence only B and C are true.
