Which of the following describes the function of a two-input AND gate?
Output is high when either or both inputs are low
Output is high only when both inputs are high✓Правильный ответ
Output is low when either or both inputs are high
Output is low only when both inputs are high
Объяснение
An AND gate outputs a high only when every input is high, so with two inputs both must be high. A gate whose output becomes low only when both inputs are high performs the inverted NAND function instead.
