Options:

Correct Answer: Two NAND gates

Solution:

A NOT operation can be created using two NAND gates.

Which gate can be used to create a NOT operation using only NAND gates?

Which gate can be used to create a NOT operation using only NAND gates?

Step 1: Understand that a NOT operation means to invert the input. If the input is true (1), the output should be false (0), and vice versa.
Step 2: Know that a NAND gate gives an output of false (0) only when both of its inputs are true (1). In all other cases, it outputs true (1).
Step 3: To create a NOT operation using NAND gates, we can connect the same input to both inputs of a NAND gate.
Step 4: Connect the input (let's call it A) to both inputs of the first NAND gate. This means the first NAND gate will receive A and A as inputs.
Step 5: The output of the first NAND gate will be NOT A (the inversion of A). If A is 1, the output will be 0, and if A is 0, the output will be 1.
Step 6: Therefore, we have successfully created a NOT operation using just one NAND gate.
