逻辑函数的代数化简法技巧剖析

Revelation for Skills of Algebraic Simplification-way on Logical Function

代数化简法可化简任意逻辑函数,但目前尚未形成一套完整系统的方法,没有一个固定的步骤可遵循,具有一定的试探性.能否尽快合理地对逻辑函数进行化简,很大程度上取决于化简者的经验、技巧、洞察力及对公式掌握与运用的熟练程度,特别是经验、技巧,如增加冗余项、配项等,一直以来是教师教学与学生学习的一个难点.将代数化简法与卡诺图化简法有机结合起来,借助卡诺图化简法,对代数化简法的应用经验与技巧作了剖析,做到有章可循.

Algebraic simplification-way can simplify any logical function. But at present complete and systematic means hasn＇t been formed and no fixed step to follow, it makes algebraic simplification-way full of probability. Whether logical function can be simplified fast and reasonably is decided by experience, skills, keen observation and degree to master and apply of formulas skillfully; Especially experience and skills, for example adding unnecessary item and etc always is one difficult point for teacher teaching and student studying, The author.combines algebraic simplification-way with Karnaugh map simplification-way happily, has the aid of Karnangh map simplification-way analyses applied experience and skills on algebraic simplification-way and attains a rule to follow.
