Question

The logic gate that performs the operation of an inverter is

• A. AND gate
• B. OR gate
• C. NOT gate
• D. NAND gate
• E. NOR gate

Hint:

While NAND and NOR gates are "Universal Gates" and can be used to \textit{build} an inverter, the NOT gate is the \textit{primary} gate that performs this function natively.

Answer 1

The Correct Option is C

Step 1: Define an Inverter

In digital electronics, an inverter is a device that outputs the opposite logic state of its input. If the input is HIGH (1), the output is LOW (0), and vice versa.

Step 2: Analyze the NOT gate

The NOT gate is a single-input, single-output gate that follows the Boolean logic \( Y = \bar{A} \).

Step 3: Check the Truth Table

Input (A)	Output (Y)
0	1
1	0

Step 4: Conclusion

Since the NOT gate "negates" or "inverts" the input signal, it is fundamentally an inverter.
