Question

In the given circuit, value of Y is

• A. $0$
• B. $\text{toggles between}0\text{and}1$
• C. Will not execute
• D. $1$

Answer 1

The correct option is A $0$



$Y=\overline{A.\overline{AB}}=\overline{\overline{AB}}+\overline{A}=AB+\overline{A}$

$\text{For A = 1, B = 0}$

$\Rightarrow Y=0+0=0$
