What logical operation does a NAND gate perform?

It produces a 0 at its output only if all inputs are 0
It produces a 1 at its output only if all inputs are 1
It produces a 0 at its output if some but not all inputs are 1
It produces a 0 at its output only if all inputs are 1Respuesta correcta

Explicación

NAND is AND followed by inversion. AND gives 1 only when every input is 1, so inverting that gives 0 only when every input is 1 and 1 for every other input combination.
