Question

In the circuit shown, A and B represent two inputs and C represents the output. The circuit represents

• A. NAND gate
• B. OR gate
• C. NOR gate
• D. AND gate

Answer 1

The correct option is B

OR gate

If either/both of the inputs are high, the corresponding diode will conduct and the output will be high. If both inputs are low, the diodes won't conduct and the output will be low. Hence, it behaves as an OR gate.
