摘要
针对高职模拟电路课程学生普遍感到难学、教师感到难教的问题,以三角波信号发生器仿真实验为例,从观察波形产生的“微观过程”循序渐进引导学生理解电路的工作过程。同时,分析了由于集成运放仿真模型及参数选择不合适造成仿真结果错误的原因和解决方法。最后对电路应用进行了仿真分析。实践证明,通过解决三角波信号发生器仿真实验存在的问题,提高了课堂效率及教学效果,深化了师生对仿真模型的认识。
For the students of high-level analog circuit courses,students generally find it difficult to learn and teachers feel difficult to teach.Taking the simulation experiment of triangular wave signal generator as an example,by observing the waveform gradually generated by the"micro-process",the paper describes how to guide students to understand the working process of the circuit.At the same time,the paper analyzes the reasons and solutions for the simulation results caused by the simulation model of the integrated operational amplifier and the inappropriate selection of parameters.Finally,the paper makes the simulation analysis of the circuit application.Practice has proved that by solving the problems existing in the simulation experiment of the triangular wave signal generator,the classroom efficiency and teaching effect are improved,and the understanding of the simulation model by teachers and students is deepened.
