If five logic gates are connected as shown in the figure, then the values of \(\mathrm{y}_1, \mathrm{y}_2\) and \(y_3\) are respectively
- A 1,1,1
- B 0,0,1
- C 1,1,0
- D 1,0,1
Answer & Solution
Correct Answer
(A) 1,1,1
Step-by-step Solution
Detailed explanation
\(y_1 = \bar{A}\) \(y_1 = \bar{0} = 1\) \(X_{AND} = y_1 \cdot B\) \(X_{AND} = 1 \cdot 0 = 0\) \(y_2 = C + X_{AND}\) \(y_2 = 1 + 0 = 1\) \(X_{NOT} = \bar{X_{AND}}\) \(X_{NOT} = \bar{0} = 1\) \(y_3 = y_1 \cdot X_{NOT}\) \(y_3 = 1 \cdot 1 = 1\) \(y_1, y_2, y_3 = 1, 1, 1\)
