Question

To get an output $Y=1$ in given circuit which of the following input will be correct.

• A. $A=1;B=0;C=1$
• B. $A=1;B=1;C=0$
• C. $A=0;B=1;C=0$
• D. $A=1;B=0;C=0$

Answer 1

Answer: (A)

$A=1;B=0;C=1$

Here the logic gates used are OR gate, AND gate. So, if we input values $0$ and $1$ to the OR gate, the output will be $1$. This output along with another input $1$ will be used as input for the AND gate. Thus, the final output is $1$.
