Question

Two logic gates are connected as shown in the figure. If the inputs are \( A = 1 \) and \( B = 0 \), then the values of \( y_1 \) and \( y_2 \) respectively are:
 

• A. \( 1, 1 \)
• B. \( 1, 0 \)
• C. \( 0, 1 \)
• D. \( 0, 0 \)

Hint:

The AND gate outputs 1 only if both inputs are 1 (\( A \cdot B \)).
- The OR gate outputs 1 if at least one input is 1 (\( A + B \)).

Answer 1

The Correct Option is B

The circuit contains two logic gates: an AND gate and an OR gate. 1. Output of \( y_1 \) (AND Gate): - The AND gate has inputs \( A = 1 \) and \( B = 0 \). - The output of an AND gate is: \[ Y_1 = A \cdot B = 1 \cdot 0 = 0 \] 2. Output of \( y_2 \) (OR Gate): - The OR gate takes inputs from \( A = 1 \) and the output of the AND gate \( Y_1 = 0 \). - The output of an OR gate is: \[ Y_2 = A + Y_1 = 1 + 0 = 1 \] Thus, the final outputs are: \[ Y_1 = 1, \quad Y_2 = 0 \] Thus, the correct answer is \(\boxed{1, 0}\).
