数字电路中巧用卡诺图

The Skillful Use of Karnaugh Map in Digital Circuit

数字电路中 ,使用卡诺图巧妙地处理一些特殊情况 ,如在无反变量输入的情况下 ,在卡诺图中应用禁止运算 ,可得到最少化的电路 ;在用中规模集成逻辑电路实现函数时 ,使用降维卡诺图可化简多变量函数 .

In Digital circuit, we can solve some special problems skillfully with Karnaugh map.For example, without the input of contravariant,we can obtain the simplest circuit by the use of inhibited operation in Karnaugh. When using MSI to implement logical functions, we can use Reduced-dimension Karnaugh Map (RDM) to simplify multi-variable functions.
