“格雷码”与“卡诺图”在逻辑函数化简中的综合运用

在数字逻辑电路的教学活动中,格雷码和卡诺图都是单独介绍的,彼此之间没有任何联系。其实,当我们仔细研究发现格雷码的组码规律时,就可以将它运用到卡诺图的化简中。本文旨在探讨讲解逻辑函数化简时,怎样将格雷码和卡诺图化简有机地结合起来,形成比较完整的教学环节,为讲解卡诺图化简提供一种直观便捷的教学思路和方法。通过自己的教学运用和实践,这一方法既便于学生迅速理解,教师讲解起来又得心应手,效果十分显著。

Synthetic Application of "Gray Code" and "Karnaugh Graph" in Logic Function Simplification

In the teaching activity of digital logic circuit, Gray Code and Karnaugh Graph are always introduced seperately, no relationship between them. While we analyzing the combined rule of Gray Code,we could use it into the simiplification of Karnaugh Graph. The purpose of the article is to discuss how to combine Karnaugh Graph with Gray Code, forming a completely teaching process when explaining the simiplification of Karnaugh Graph, providing a more directive and promotive teaching mind and method to it. By teaching and practicing in myself classes, this method can be understood quickly by students, analyzed by teachers easily, making a great effction.
