| 摘 要： | 逻辑函数是分析和设计数字电路的数学依据和基础,用化简后的表达式构成逻辑电路可节省器件,降低成本,提高工作的可靠性,因此将逻辑函数化简为最简式是至关重要的.一般情况下,最简式的判断无一定律可遵循,比较困难.本文介绍了三种判断逻辑函数最简式的依据,并将其实用性在"代数法"、"卡诺图法"两种化简方法中分别进行了举例说明.

| Abstract: | Logical function is the bas of anylyzing and designing digital circuits,Using the simplified logical function to design digital circuits can save circuit elements,reduce cost,and important to simplicity digital function into the simplest form,but the judgement rules of the simpiest form has not been summarized.This paper shows three ways to judge if the logical fuction has been simplified into the simplest form. |
