In a certain 2 -inputs logic gate, when inputs A = 0 and B = 0, then output C = 1. And also when inputs A = 0, B = 1, then again output C = 1. The gate must be (a) OR (b) AND (c) NAND (d) NOR

Answer: (c). (0, 0) gives 1: OR and AND give 0, so it is NAND or NOR. (0, 1) gives 1: NOR gives 0, NAND gives 0 · 1 = 1. So the answer is (c) NAND.

In a certain 2 -inputs logic gate, when inputs $\mathrm{A} = 0$ and $\mathrm{B} = 0$ , then output $\mathrm{C} = 1$ . And also when inputs $\mathrm{A} = 0,\ \mathrm{B} = 1$ , then again output $\mathrm{C} = 1$ . The gate must be

Show answer and solution

Answer: (c)

(0, 0) gives 1: OR and AND give 0, so it is NAND or NOR.
(0, 1) gives 1: NOR gives 0, NAND gives $\overline{0 \cdot 1} = 1$ .
So the answer is (c) NAND.
