NOT gate

The function of a NOT gate is to pass the input signal unchanged.

The function of a NOT gate is to invert the input signal.

The function of a NOT gate is to combine multiple input signals.

The function of a NOT gate is to amplify the input signal.

| A | B | Output | |---|---|--------| | 0 | 0 | 0 | | 0 | 1 | 0 | | 1 | 0 | 1 | | 1 | 1 | 0 |

| A | B | Output | |---|---|--------| | 0 | 0 | 0 | | 0 | 1 | 1 | | 1 | 0 | 1 | | 1 | 1 | 1 |

| A | B | Output | |---|---|--------| | 0 | 0 | 1 | | 0 | 1 | 1 | | 1 | 0 | 0 | | 1 | 1 | 1 |

| A | B | Output | |---|---|--------| | 0 | 0 | 1 | | 0 | 1 | 0 | | 1 | 0 | 0 | | 1 | 1 | 0 |

An XOR gate outputs true for any true input, while an OR gate requires all inputs to be true.

An XOR gate differs from an OR gate in that it requires an odd number of true inputs to output true, whereas an OR gate outputs true for any true input.

An XOR gate can only have one input, whereas an OR gate can have multiple inputs.

An XOR gate outputs false when both inputs are true, while an OR gate outputs true in the same case.
