Question

For the given circuit, the output \( Y \) is: 

• A. 0
• B. 1
• C. A
• D. \( \overline{A} \)

Hint:

In logic gate combinations, XOR gates can act as NOT gates when configured with repeated input signals. Always trace signal flow carefully through each gate.

Answer 1

The Correct Option is D

Step 1: Identify the logic gates.
The given circuit contains a combination of XOR and NOT gates. The configuration shows two XOR gates connected such that the output of the first XOR feeds into the second.
Step 2: Analyze the logic.
For XOR gate, the output is 1 when inputs are different and 0 when inputs are the same. If both XOR gates receive the same signal arrangement, the result effectively complements the input.
Step 3: Simplify the circuit.
By Boolean simplification or truth table analysis, the final output \( Y \) is the logical NOT of input \( A \). \[ Y = \overline{A}. \] Step 4: Final Answer.
Hence, the circuit output is \( \overline{A} \).
