Logic gates are electronic circuits used to perform certain logical operations. The commonly used gates are: AND, OR, NOT, NAND and NOR. Each logic gate is indicated by a symbol and its function is defined by a truth table. The flow of current or signal is controlled using these gates. These are basic components of digital electronic devices.
We can identify different logic gates by their truth table. The truth table of each logic gate is different from another one.
