【摘要】 文献中一般是针对SSI小规模组合电路竞争冒险进行分析,然而,实际上中规模组合电路也常出现竞争冒险现象.以74LS138组成函数发生器为例,利用卡诺图和Multisim仿真软件来进行分析,并且给出消除译码器竞争冒险的方法.更多还原

【Abstract】 In general,ones perform analysis on the competition adventure with SSI small- scale combinational circuit in the literature. However,in fact,the middling- scale combinational circuit also often occur in the competition adventure. In this paper,as example,taking the composition 74LS138 function generator,by use of the Karnaugh maps and Multisim simulation software,the authors perform analysis and give some method which can eliminate the competition risky of decoder.更多还原
