摘要
根据反演规则和对偶规则定义,给出了反演卡诺图和对偶卡诺图,进而利用反演卡诺图和对偶卡诺图将逻辑函数“或与”表达式化简及化成“与或”表达式,很适于用“或非”门实现的电路分析和化简.
Complementary opration karnaugh map and duality karnaugh map are defined and gived by complementary opration theorem and duality theorem. Logic function 'OR - AND' expression are simplified and converted to 'AND- OR' expression by complementary opration karnaugh map and duality karnaugh map. It is applicable to analyse and simplify the logic circuit composed 'NOR' gates.
