Question
Which of the following is a universal gate ?
The correct answer is
NAND
Understanding Universal Gates
A universal gate is a fundamental building block in digital electronics. It's a logic gate that allows any other logic gate (like AND, OR, NOT) and consequently any digital circuit to be constructed using only that type of gate.
There are two primary types of universal gates:
- NAND (Not AND)
- NOR (Not OR)
Identifying the Universal Gate
The question asks to identify a universal gate from the given options: AND, OR, NAND, and Inverter (NOT gate).
- AND, OR, and Inverter gates are basic gates, not universal gates.
- The NAND gate is known to be a universal gate because it's possible to create AND, OR, and NOT logic functions solely by using NAND gates.
Therefore, the NAND gate is the correct answer.
