Multisim和Excel在谐振电路实训教学中的应用

Application of multisim and excel in practice teaching of the resonant circuit

在分析串联电路谐振特性时由于测试仪器的限制,导致在传统实训教学中,难以实时监测电路中电感和电容的电压响应随激励频率变化的动态过程。而利用Multisim可以实现对串联电路谐振特性的仿真测试,并将测试结果用Excel图表功能绘制出理想的谐振曲线,从而准确直观地揭示出串联电路选频特性的实质,对传统实训教学起到很好的补益作用。

On the analysis of the series circuit when the resonant ctmla testing instruments, lead to in traditional practice teaching, it is difficult to real-time monitor circuit inductance and capacitance voltage in response to the dynamic process of changing with excitation fre- quency. And the use of Multisim can realize the simulation test, the characteristics of the series reso- nant circuit, and the test results in excel chart function to map the ideal resonance curve, accurately and intuitively reveal the series circuit, the essence of the frequency selective characteristics, the tradi- tional practice teaching have very good tonic effect.
