Logic Gates

Logic gates are the building blocks of digital electronics and are used to build telecommunication devices, computers, etc.

AND Gate

The truth table for the AND gate is below:

OR Gate

The truth table for the OR gate is below:

NOT Gate

The truth table for the NOT gate is below:

Combining NOT gate with AND and OR gates

The NOT gate can be combined with the AND and OR gates to produce a different output.

NAND Gate

NAND = NOT AND. The NAND gate corresponds to an AND gate followed by a NOT gate.

The truth table for the NAND gate is below:

NOR Gate

NOR = NOT OR. The NOR gate corresponds to an OR gate followed by a NOT gate.

The truth table for the NOR gate is below:
