Question

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

 

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

Hint:

For logic gates, remember that: - The AND gate outputs 1 if both inputs are 1, else it outputs 0. - The NAND gate outputs 0 if both inputs are 1, else it outputs 1.

Answer 1

The Correct Option is B

For the given combination of logic gates:
First gate performs an AND operation, and since both inputs are \( A = 1 \) and \( B = 1 \), the output of the first gate (\( y_1 \)) will be \( 1 \).
The second gate performs a NAND operation, and since the input is \( A = 1 \) and \( B = 1 \), the output of the second gate (\( y_2 \)) will be \( 0 \).
Thus, the values of \( y_1 \) and \( y_2 \) are \( 0, 1 \), respectively.
