Q129 / 180 · KCET 2019 · Physics
In the following circuit, what are \( P \) and \( Q \) ?
- Correct answerA\( P=0, Q=1 \)
- B\( P=0, Q=0 \)
- C\( P=1, Q=1 \)
- D\( P=1, Q=0 \)
Solution
(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, \( B=0 \therefore Q=1 \)
Hence, the correct answer is option: 'A'.
