摘要
针对模拟电路实验教学中存在的普遍问题,以"文氏电桥振荡"实验为例,将虚拟仿真软件Multisim应用到模拟电子实验教学中。借助软件的电路仿真功能,可直观形象地演示电路特性变化,如:改变电路的结构和参数等,增强了学生对复杂抽象的模拟电路理论知识的感性认识。在此基础上,针对模拟电子技术课程中的教学难点,实例阐述结合虚拟仿真的教学内容设计,对于学生深刻理解文氏电桥振荡器这部分的内容具有重要意义。将虚拟仿真技术应用于模拟电子实验课程教学是对传统教学方法和教学手段的有效补充,学生不只是观察波形产生的"结果",更是体会波形产生的"微观过程",进一步做到了理论联系实际。
Aiming at the common problems in the experimental teaching of analog circuits,the Multisim virtual simulation software is applied to the simulation experiment of"Wien-bridge oscillation".With the help of the software simulation function,it can visualize the deformation of the circuit,such as changing the structure and parameters of the circuit,and enhance the students’knowledge of the complex analog circuit theory.Based on this,it is of great significance for students to deeply understand the contents of the Wien-bridge oscillator in order to solve the teaching difficulties in the simulation electronic technology course and to illustrate the teaching content design combined with the virtual simulation.The application of virtual simulation technology to the teaching of analog electronic experiment is an effective supplement to the traditional teaching methods.Students not only observe the"result"of the waveform,but also realize the"microscopic process"of the waveform,and do further the theoretical connection actual.
