Question

For the circuit shown above, the equivalent gate is:

 

• A. AND gate
• B. OR gate
• C. NAND gate
• D. NOT gate

Hint:

When combining logic gates, follow the sequence of operations and remember that a NOT gate inverts the output of the gate it is connected to. An AND gate followed by a NOT gate is equivalent to a NAND gate.

Answer 1

The Correct Option is C

Looking at the circuit: - The circuit consists of two gates: an AND gate and a NOT gate (in the form of an inverter). 
- The inputs \( A \) and \( B \) are first passed through the AND gate. 
- The output of the AND gate is then passed through a NOT gate (inverter). This combination of an AND gate followed by a NOT gate is equivalent to a NAND gate, as the NAND gate is the negation of the AND gate. Thus, the equivalent gate is a NAND gate.
