透过抢答器看Multisim在数字电路教学中的应用

摘要

In the digital circuit teaching of information technology profession in higher vocational school, the greatest dififculty is that part of students do not get enough basis knowledge which leads to the obstacle in understanding abstract knowledge. With the visualized feature of the EDA technology, Multisim provides a good environment for turning abstract thinking to image thinking in digital circuit teaching. Responder.utilizing 74LS175 chip as the core components, is very appropriate as a comprehensive teaching case of digital circuit for its more complete comprehensive knowledge , the simplicity of the combination circuit, the adaptability of the circuit structure and good functionality of the whole device. Due to the visual, intuitional, vivid and interesting process, it is become easier for students to understand the principle of digital circuit.%在高职高专信息技术专业的数字电路教学中，遇到的最大困难是部分学生的基础底蕴不深，在对抽象知识的理解上有障碍。Multisim以EDA技术特有的直观形象特性，为将数字电路教学中的抽象思维转化为形象思维提供了极其良好的环境。以74LS175芯片为核心器件设计的抢答器，以其较为完备的知识综合性、电路组合的简单性、线路结构的适应性、整个装置的良好功能性，作为数字电路的综合教学案例是十分适宜的。由于展示过程形象、直观、生动、有趣，使学生理解数字电路原理的过程变得简单。
