第三节 2.逻辑运算
<h2>“非”门电路: NOT !</h2>
<p>先来说最简单的门电路非门
“非”乃“反”也，在电路中起到取反的作用，在电路中即为有0出1，有1出0</p>

<h2>“与”门电路: AND &</h2>
<p>与门电路只有当条件全都具备时才会有所动作，在电路中即为有0出0，全1出1</p>

<h2>“或”门电路: OR |</h2>
<p>或门电路只要符合一个条件时就会有所动作，在电路中即为有1出1，全0出0</p>

<h2>“异或”门电路: xor ^</h2>
<p>异或门电路内部是由与门，或门，非门所共同组成的组合门电路，在电路中即两输入信号相同出0，不同出1
