All Logic Gates

What are Logic Gates:

Logic gates are fundamental building blocks of digital circuits. They perform logical operations on one or more binary inputs (0s and 1s) and produce a binary output based on their predefined behavior. There are several types of logic gates, each with its own unique functionality. Let's explore them:

1. AND Gate:

The AND gate takes two or more inputs and produces an output that is HIGH (1) only if all the inputs are HIGH. Otherwise, the output is LOW (0). The symbol for an AND gate is a triangle with a dot at the intersection of the inputs, and the output is represented by a single line.

2. OR Gate:

The OR gate also takes two or more inputs, but it produces an output that is HIGH (1) if at least one input is HIGH. The output is LOW (0) only when all the inputs are LOW. The symbol for an OR gate is a plus sign (+), and the output is represented by a single line.

3. NOT Gate (Inverter):

The NOT gate has a single input and produces the opposite output. If the input is HIGH (1), the output is LOW (0), and vice versa. The symbol for a NOT gate is a triangle with a small circle at the input, and the output is represented by a single line.

4. NOR Gate (NOT OR):

The NOR gate takes two or more inputs and produces an output that is HIGH (1) only if all the inputs are LOW. If any of the inputs are HIGH, the output is LOW (0). The symbol for a NOR gate is a plus sign (+) with a small circle at the output.

5. NAND Gate (NOT AND):

The NAND gate is a combination of the AND gate followed by a NOT gate. It takes two or more inputs and produces an output that is the inverse of the AND gate's output. The output is LOW (0) only if all the inputs are HIGH; otherwise, it is HIGH (1). The symbol for a NAND gate is an AND gate followed by a small circle at the output.

6. XOR Gate (Exclusive OR):

The XOR gate takes two inputs and produces an output that is HIGH (1) if the inputs are different. If the inputs are the same, the output is LOW (0). The symbol for an XOR gate is a plus sign with a circle around it.

7. XNOR Gate (Exclusive NOR):

The XNOR gate is a combination of the XOR gate followed by a NOT gate. It takes two inputs and produces an output that is the inverse of the XOR gate's output. The output is HIGH (1) if the inputs are the same; otherwise, it is LOW (0). The symbol for an XNOR gate is an XOR gate followed by a small circle at the output.
