This document discusses different types of logic gates. It defines a logic gate as an electronic circuit that makes logical decisions and performs logical operations. There are two main types of logic gates - basic gates which include AND, OR, and NOT gates, and universal gates which include NAND, NOR, and XOR gates. Each gate is then defined, such as the AND gate performing logical multiplication, the OR gate performing logical addition, and the NAND gate being the complement of the AND gate. Truth tables are also provided for gates like the XOR gate.

- 2. Logic Gates A Logic gate is an electronic cercuit which makes logical decisions, and perform logical operation is called logic gates.
- 3. Type of logic gates BASIC GATES UNIVERSAL GATES 1. AND GATE 1. NAND GATE 2. OR GATE 2. NOR GATE 3. NOT GATE 3. XOR GATE There are two types of logic gates
- 4. AND GATE AND gate perform logical multiplication. Operation =( A.B ) AND gate have two or more than two input and one output.
- 6. OR GATE OR gate perform logical addition . Operation = (A+B) . OR gate have two or more than two input and one output.
- 8. NOT GATE Not gate perform logical complement function. purpose of Not gate is to convert one logical operation into its opposite is called NOT GATE.
- 9. NAND GATE NAND gate is combination of NOT-AND gate. I.e. it is complement of AND gate. It has two or more than two inputs and only one output.
- 11. NOR GATE NOR gate is combination of NOT-OR gate. i.e. it is complement of OR gate. It has two or more than two inputs and only one output.
- 13. XOR GATE(exlusive-or gate) XOR gate is a gate with two or more inputs and one output. The XOR gate has a high output only when an odd no. of inputs are high.
