Logic Gates question from NEET 2016 (Phase 2)

Q155NEET 2016 · PHASE 2Medium

Logic Gates

What is the output Y in the following circuit, when all the three inputs A, B, C are first 0 and then 1?

Show answer and solution

Answer: (c)

P is AND, Q is NAND: $Y = \overline{(A \cdot B) \cdot C}$ .
All 0: $Y = \overline{0} = 1$ . All 1: $Y = \overline{1} = 0$ .
So the answer is (c) 1, 0.
