摘要
针对传统高频电路实验箱实践教学的不足,分析了应用电路仿真软件辅助实验教学的必要性,通过运用Multisim对二极管包络检波电路进行虚拟仿真实验,研究了二极管包络检波电路正常检波情况、惰性失真现象以及负峰切割失真现象等。通过不断地改变电路元件的参数进行对比观察得到二极管检波电路的相关特性,虚拟仿真实验结果和理论分析计算结果相一致。实践证明,将Multisim应用于高频电子线路仿真实验教学,可以克服实验教学中仪器仪表的不足以及各种干扰现象,使实验更加灵活,更具有创新性,也有利提高学生的学习的积极性和主动性。
In view of the deficiencies in the traditional practice teaching of high frequency cuit experiment box, this paper analyzes the application of circuit simulation software in experimental teaching, h studies tile high frequency resonant power amplifier circuit in undervohage overwhage conditions, etc. The resuh indicates that virtual simulation experiment results conform to theoretical calculation results. Practice proves that the apptisim in the simulation experimental teaching of high frequency electronic circuits can overcome the deficienies in the experimental teaching instruments and different kinds f interferences, making the experiment more flexible, more innnvative, which can arouse students' learning enthusiasm and initiative.
