Universal Logic Gate Experiments 通用逻辑门实验

Universal logic gate designs (NAND, NOR) are more sophisticated than the basic logic gates (AND, OR, & NOT) that they are based on. These two logic gates take the OUTPUT from one logic gate and then feeds it into another logic gate as an INPUT. With the combination of multiple basic logics the output of the AND, or from the OR gates can be negated using the NOT gate to produce the NAND (NOT – AND) and NOR (NOT – OR) logics respectively.

通用逻辑门设计（NAND、NOR）比基本逻辑门（AND、OR和NOT）要复杂。这些复合逻辑从一个逻辑门获取输出，然后将其作为输入馈入另一个逻辑门。通过组合多个基本逻辑，“与”、“或”门的输出可以使用“非门”来分别组成“与非”（NOT-AND）和“非门”（NOT-OR）逻辑。

Simplified Compound Logic Gate Designs 简化的复合逻辑门设计

Once you understand how compound logic gates such as the NAND, NOR you can create any number of digital circuits. Even more advanced circuits such as the XOR and XNOR gates can be created by using a combination of simple logic gates using the same approach. However, once you understand how to build complex logical sequences you can then start learning how to simplify the circuitry by researching and experimenting with more efficient ways to produce the same logical outcome using fewer components. This results in a much simpler circuit design; however, the theory behind these new circuits will be much more sophisticated despite the circuits being far more streamlined.

一旦了解了NAND等复合逻辑门的工作原理，就可以创建任意数量的数字电路，甚至更高级的电路，如XOR和XNOR门。在了解了如何构建复杂的逻辑序列，就可以开始学习如何通过研究和试验更有效的方法来简化这些复杂电路，从而使用更少的组件生成相同的逻辑结果。这使得电路设计简单得多，尽管电路已精简，但是其背后的理论是很复杂的。
