In the following circuit, what are \( P \) and \( Q \) ?
- A \( P=0, Q=1 \)
- B \( P=0, Q=0 \)
- C \( P=1, Q=1 \)
- D \( P=1, Q=0 \)
Answer & Solution
Correct Answer
(A) \( P=0, Q=1 \)
Step-by-step Solution
Detailed explanation
(A)
For both NOR gates \( Y=(\bar{A}+\bar{B}) \)
For gate \( 1, A=1 \therefore P=0 \)
For gate 2, \( B=0 \therefore Q=1 \)
For both NOR gates \( Y=(\bar{A}+\bar{B}) \)
For gate \( 1, A=1 \therefore P=0 \)
For gate 2, \( B=0 \therefore Q=1 \)
