Question

Consider the circuit shown below and find the minimum number of NAND gates required to design it. 

• A. 4
• B. 6
• C. 3
• D. 5

Hint:

To design logic gates using NAND gates, refer to standard combinations for each gate and the number of gates required for implementation.

Answer 1

The Correct Option is A

The circuit shown is an OR gate with two inputs A and B. To implement this OR gate using NAND gates, we can use the following logic: - A single NAND gate can be used to perform the NOT operation. - By combining NAND gates, we can design any basic gate. For an OR gate, the design requires 4 NAND gates. Thus, the minimum number of NAND gates required to design the OR gate is \( \boxed{4} \).
