# Digital `Logic Gates`

symbols and truth table.

Fundamental Logic Gates in digital electronics. Lets start with truth table for **AND, OR, XOR and NOT **gates below.

X (input 1) |
Y (input 2) |
Z (AND out) |
Z (OR out) |
Z (XOR out) |

0 | 0 | 0 | 0 | 0 |

0 | 1 | 0 | 1 | 1 |

1 | 0 | 0 | 1 | 1 |

1 | 1 | 1 | 1 | 0 |

**Gate 1:- AND Gate**

Description: This gate is fundamental of any operation where output is dependent on product of all binary inputs.

Output = Input1 * Input2 …….. * Input N

Where, outputs and inputs are all in binary values ’1’ or ’0’
