本文给出了有关状态变化过程的几个定义,得到了逻辑函数在状态变化过程中所要遵循的重要规律,导出了三变量逻辑函数之最短K_(min)=2全状态变化过程,为研究数字电路正常工作和可能出现的异常情况提供了最有用的工具和方法。
In this paper, we give some definitions about the process of state change, and get the important rules to be followed in the state process of logic function. Then the shortest K_ (min) = 2 full state process of three-variable logic function is derived. The most useful tools and methods are provided by the normal operation of the circuit and possible abnormalities.
