One of the following values of inputs A, B and C respectively gives output (Y) of the following combination of logic gates as ' 1 ' is (a) 0, 0, 0 (b) 0, 1, 0 (c) 1, 0, 0 (d) 1, 0, 1

Answer: (d). OR gate gives B + C; AND with A gives Y = A · (B + C). Y = 1 needs A = 1 and at least one of B, C equal to 1. (a), (b) have A = 0; (c) has B + C = 0; (d) 1 · (0 + 1) = 1. So the answer is (d) 1, 0, 1.

Logic Gates

One of the following values of inputs $\mathrm{A}, \mathrm{B}$ and C respectively gives output $(\mathrm{Y})$ of the following combination of logic gates as ' 1 ' is

Show answer and solution

Answer: (d)

OR gate gives $B + C$ ; AND with A gives $Y = A \cdot (B + C)$ .
Y = 1 needs $A = 1$ and at least one of $B, C$ equal to 1.
(a), (b) have $A = 0$ ; (c) has $B + C = 0$ ; (d) $1 \cdot (0 + 1) = 1$ .
So the answer is (d) $1, 0, 1$ .
