LOGIC GATES
AND Gate
- Logic gates are the basic building blocks of any digital system.
- It is an electronic circuit having one or more than one input and only one output.
- The relationship between the input and the output is based on a certain logic.
- Based on this, logic gates are named as AND gate, OR gate, NOT gate etc.
AND Gate
- A circuit which performs an AND operation is shown in figure. It has n input (n >= 2) and one output.
OR Gate
- A circuit which performs an OR operation is shown in figure. It has n input (n >= 2) and one output.
NOT Gate
- NOT gate is also known as Inverter. It has one input A and one output Y.
NAND Gate
- A NOT-AND operation is known as NAND operation. It has n input (n >= 2) and one output.NAND Gate
- A NOT-AND operation is known as NAND operation. It has n input (n >= 2) and one output.
NOR Gate
- A NOT-OR operation is known as NOR operation. It has n input (n >= 2) and one output.
XOR Gate
- XOR or Ex-OR gate is a special type of gate.
- It can be used in the half adder, full adder and subtractor.
- The exclusive-OR gate is abbreviated as EX-OR gate or sometime as X-OR gate.
- It has n input (n >= 2) and one output.XOR Gate
XNOR Gate
- XNOR gate is a special type of gate.
- It can be used in the half adder, full adder and subtractor.
- The exclusive-NOR gate is abbreviated as EX-NOR gate or sometime as X-NOR gate.
- It has n input (n >= 2) and one output.
