摘要
卡诺图是一种表示逻辑函数邻近关系的图形,多用于逻辑函数的化简。本文通过图形和实例形象地描述卡诺图基本应用中的注意事项和使用技巧,及其特殊应用——判明函数关系:相等或者互补,进行与、或、异或、同或逻辑运算,在逻辑电路中消除竞争和冒险的方法。卡诺图的灵活应用可以大大简化数字电路的分析和设计过程,它能比很多现有常规方法更简单快捷的解决问题,为逻辑电路的应用打开新的窗口。
Karnaugh map is a kind of diagram expressing the proximity relation of logic functions,and it is mostly used for simplification of logic functions. This paper symbolically depicts the cautions and use skills in basic application of Karnaugh map through graphs and examples,as well as its special application-discrimination of function relationship： equal or complementary,and,or,xor,x nor logic operation,elimination of competition and risk in logic circuits. Through the flexible application of Karnauph map,the analysis and design process of digital circuits can be simplified greatly,and it can solve the problems more simply and more quickly than many existing conventional methods,and open a new window for application of logic circuits.
