英语翻译写一篇门电路的介绍,要简明,不要太复杂,要写翻译

门电路
“门”是这样的一种电路：它规定各个输入信号之间满足某种逻辑关系时,才有信号输出,通常有下列三种门电路：与门、或门、非门（反相器）.从逻辑关系看,门电路的输入端或输出端只有两种状态,无信号以“0”表示,有信号以“1”表示.也可以这样规定：低电平为“0”,高电平为“1”,称为正逻辑.反之,如果规定高电平为“0”,低电平为“1”称为负逻辑,然而,高与低是相对的,所以在实际电路中要选说明采用什么逻辑,才有实际意义,例如,负与门对“1”来说,具有“与”的关系,但对“0”来说,却有“或”的关系,即负与门也就是正或门；同理,负或门对“1”来说,具有“或”的关系,但对“0”来说具有“与”的关系,即负或门也就是正与门. Gate
"The Gate" is such a circuit: it provides among the various input signals to meet a certain logic, the only signal output, usually the following three gates: and the door, or doors, non-gate (inverter) . From the logic relations, the gate circuit input or output only two states, and no signal to "0" indicates that the signal to "1". It can also be provided: low to "0", high "1", referred to as positive logic. Conversely, if the requirement is high for the "0" low level "1" referred to as negative logic, however, is relatively high and low, so the actual circuit used to explain what the election logic
Have practical significance, for example, negative and gate of the "1", it has an "and" relationship, but "0" for there "or" relationship, that is, negative and gate is positive or doors; Similarly, negative, or doors of the "1", it has an "or" relationship, but "0" for a "and" relationship, that is negative or door with the door.
