在中职学校电子技术基础作为三校生高考的四大基础课程之一,是工科类专业的必学理论部分。而电子组合电路中是电子技术基础数字部分中的基本模块,由逻辑逻辑真值表归纳逻辑表达式是该模块中的重点与难点,解决这个问题不仅是理论的需要,还是学生实际操作设计电路的要求。本人通过多年的教学经验,结合中职生知 Electronic technology in secondary vocational schools as the three basic entrance exams of the four basic courses, engineering major is the necessary theoretical part. The electronic combination circuit is the basic digital part of the basic electronic technology module, the logic of the logical truth table summarizes the logic expression is the focus of the module and difficult to solve this problem is not only the theory needs, or the actual operation of the design circuit Request. I have many years of teaching experience, combined with secondary vocational students know
