Question

The circuit diagram shown here corresponds to the logic gate,

• A. NOR
• B. AND
• C. OR
• D. NAND

Answer 1

The Correct Option is A

To determine which logic gate is represented by the given circuit diagram, let's analyze the characteristics and behavior of each option and identify which one matches the logic of the circuit.

Step-by-Step Logic Analysis:

1. First, recall the basic properties of the logic gates provided in the options:
   • NOR Gate: It is a combination of an OR gate followed by a NOT gate. Output is true (0) only when all inputs are false (0).
   • AND Gate: Output is true (1) only when all inputs are true (1).
   • OR Gate: Output is true (1) when at least one input is true (1).
   • NAND Gate: It is a combination of an AND gate followed by a NOT gate. Output is false (0) only when all inputs are true (1).
2. To correctly identify a NOR gate in a circuit, the circuit should consist of an OR operation followed by a NOT operation.
3. The question indicates the circuit diagram corresponds to one of these logic gates. Given that the correct answer is indicated as NOR, the circuit diagram must reflect this behavior.
4. In a typical NOR gate:
   • Input conditions are such that the output is 0 if either or both of the inputs are 1 and output will be 1 if both inputs are 0.
   • If a diagram would show two inputs leading to an OR gate, followed by a NOT operation, it is a NOR gate.

Conclusion:

Among the options, the description that best fits a NOR gate is correct as it will have an OR gate functionality inverted by a NOT gate to provide outputs based on the described logic.

Final Answer:

The circuit diagram corresponds to the NOR gate, as concluded from the given information and logic characteristics.
