针对机电专业学生对数字电路组合逻辑电路的分析与设计比较困难,特别是逻辑电路设计难以下手,我从分析逻辑图从逻辑式化简到真值表再到分析功能,使学生看懂逻辑电路图,而设计逻辑图从逻辑要求到例出真值表、写出逻辑式、化简,最后形成逻辑电路图,分析与综合这相反的过程进行了论证,并例举了两个例子说明。 For mechanical and electrical majors in digital circuit combinational logic circuit analysis and design more difficult, in particular, the logic circuit design is difficult to start, I analyze the logic diagram from the logic of the simplified form to the truth table to the analysis function, so that students understand the logic diagram , And the design logic diagram from the logic requirements to the truth table, write logic, simplify, and finally form a logic circuit diagram, analysis and synthesis of the opposite process was demonstrated, and illustrates two examples.
