摘　　要：卡诺图是逻辑电路中非常重要的分析工具,简单、直观、便于使用的特点使其在逻辑电路中有着广泛应用.现行的教材中虽然都介绍了相关的知识,但篇幅都不是很大,使得初学者不能系统地掌握卡诺图的应用.卡诺图不仅可以应用于逻辑函数的化简,还可以应用于逻辑函数表达式形式的变换、实现逻辑函数的运算、判断和消除逻辑电路的竞争冒险等.笔者通过具体实例,介绍了卡诺图在数字逻辑电路中的应用,体现了卡诺图的实用性.系统地掌握卡诺图的应用可以使学习者在学习过程中达到事半功倍的效果.The Karnaugh map is a very important analysis tool of digital electronic circuit.Because of its unique simplicity and direct-viewing,it works easily and has been widely applied in the digital electronic circuit.In the current teaching material,it has been covered,but not enough to systematically grasp the applications of the Karnaugh map for beginners.The Karnagh map can be used not only to simplify the operation of logic functions,also to transform the expression type of the logic function.It can be applied not only to logic operation of two logic functions,also to judge and remove in the phenomenon of race and hazard of the combinational logic circuit.The writer systematically introduces the application of the Karnaugh map with examples.The learner will gain double pay in the learning process,if he systematically comprehends the application of the Karnagh map.
