Question

The logic function implemented by the circuit shown in the Figure below is (ground implies a logic '0')

• A. \( F = \text{XOR}(P, Q) \)
• B. \( F = \text{OR}(P, Q) \)
• C. \( F = \text{XNOR}(P, Q) \)
• D. \( F = \text{AND}(P, Q) \)

Hint:

In circuits with gates, remember that XOR gates produce a '1' when the inputs differ and a '0' when the inputs are the same.

Answer 1

The Correct Option is A

The circuit shown is an XOR gate implementation. An XOR gate outputs a logic '1' when exactly one of the inputs is '1', and '0' otherwise. The ground indicates a logic '0' level, which is characteristic of an XOR gate. Therefore, the correct answer is option (1).
