Refer to the logic circuit given below. For two inputs (A=1, B=1)...
Refer to the logic circuit given below. For two inputs and , output will be __________.

Options
- A respectively
- B respectively
- C respectively
- D respectively
Correct answer
C. respectively
Step-by-step solution
From the given logic circuit, we can determine the Boolean expression for the output .
The output of the NOT gate is .
The inputs to the OR gate are and , so its output is .
The inputs to the AND gate are and , so its output is .
These two outputs are fed into a NOR gate. The final output is given by:
Simplifying the Boolean expression:
Using De Morgan's laws:
Now, we evaluate for the given input combinations:
For :
For :
Therefore, the outputs are and respectively.
