请翻译这句(关于数电方面的)
The NOT gate is essentially an inverter and it provides
the complement of the logic variable connected to its input

非门实质上是一个反相器,它为它的逻辑输入提供相反值.
这个句子里面compliment本意是补充的意思,但是在数理逻辑里面是相反的意思.你可以看看这个解释:
(logic) An expression related to some other expression such that it is true under the same conditions that make other false,and vice versa
