关于逻辑函数的卡诺图化简法的几个问题

A Few Problems in the Simplification of Logic Function Using Karnaugh Maps

用卡诺图化简逻辑函数时 ,合并的最小项方法若有两种以上的 ,要比较、检查才能得出其最简逻辑函数表达式 ,且结果不具有惟一性。

When simplifying a logic function using Karnaugh Maps, if there are more than one method to combine its minters, one must examine and compare them to find out the simplest expression of the logic function, and even so the conclusion may not be exclusive.
