In a given logic circuit, the output Y when all the three inputs A, B, C are first low and then high will be respectively (a) (0, 0) (b) (0, 1) (c) (1, 0) (d) (1, 1)

Answer: (c). Y = A + B · C (NOT on A, NAND on B, C, then OR). All low: Y = 1 + 0 = 1. All high: Y = 0 + 1 = 0. So the answer is (c) (1, 0).

In a given logic circuit, the output Y when all the three inputs $\mathrm{A}, \mathrm{B}, \mathrm{C}$ are first low and then high will be respectively

Show answer and solution

Answer: (c)

$Y = \bar{A} + \overline{B \cdot C}$ (NOT on A, NAND on B, C, then OR).
All low: $Y = 1 + \overline{0} = 1$ .
All high: $Y = 0 + \overline{1} = 0$ .
So the answer is (c) $(1, 0)$ .
