The output Y of the following digital logic circuit will be '1' (one) for the inputs (a) A = 1, B = 0, C = 0 (b) A = 1, B = 0, C = 1 (c) A = 1, B = 1, C = 0 (d) A = 1, B = 1, C = 1

Answer: (d). Circuit: Y = A + B · C. All options have A = 1, so A = 0 and Y = B · C. Y = 1 needs B = 1 and C = 1. So the answer is (d) A = 1, B = 1, C = 1.

The output Y of the following digital logic circuit will be '1' (one) for the inputs

Show answer and solution

Answer: (d)

Circuit: $Y = \overline{A} + B \cdot C$ .
All options have $A = 1$ , so $\overline{A} = 0$ and $Y = B \cdot C$ .
$Y = 1$ needs $B = 1$ and $C = 1$ .
So the answer is (d) $A = 1, B = 1, C = 1$ .
