摘要
本文对逻辑设计中现行的卡诺图法作了重大改进,提出了不列真值表而用直读式卡诺图直接描述组合逻辑系统和程序确定型时序逻辑系统的新方法。同时,根据对直读式卡诺图的轴对称性的分析,提出并论证了在这种图中确定逻辑函数蕴含项和实质蕴含项的新法则。这种改进的卡诺图法比现行的卡诺图法简便,其适用范围更广。
In this paper,the current Karnaugh Map Method for logic design has been improved greatly.The author suggests a new method describing directly,with a direct-reading Karnaugh Map,combina- tional logic systems and sequential logic systems in which the sequences are definite without making a llst of true table.At the same time,on the basis of analysing the axisymmetric quality of the direct-reading Karnaugh Map,he suggests and demonstrats new rules of determining the implicit items and substantial implicit items of logic function in that map.The improved Karnaugh Map Method is more simple and convenient than the current one,and is more extensively used.
