关于数字逻辑课程教学方法与手段改进的探讨

摘要

针对数字逻辑课程中逻辑代数和时序逻辑电路章节的部分内容比较抽象，中规模通用集成电路章节电路结构和功能讲解时不够形象和直观的问题，探讨如何从教学方法和教学手段上进行改进，提出用“下标计算法”简化逻辑函数表达式的转换过程，在同步时序逻辑电路设计时用“趋势分析法”建立正确的原始状态图，引入Proteus软件对各种中规模数字逻辑电路进行仿真，使电路讲解更加生动，进而提高课程教学效果。%Aiming to the problems that the partial contents of logic algebra and sequential logic circuit chapter in the digital logic course are relatively abstract and the explanations to the circuit structures and functions in the chapter of general medium scale integrated circuit are not visual and intuitional enough. It is discussed that how to solve the problems by the teaching methods and teaching means. So the method of subscript calculation is proposed to simplify the conversion process of logic function expressions and trend analysis method is used to establish the correct original state diagrams during the design of synchronous sequential logic circuits. At the same time, the software Proteus is introduced to emulate kinds of medium scale digital logic circuits. The emulation by Proteus can make the explanations of the circuit more vivid and then enhance the curriculum teaching effect.
