摘要
针对传统高频电路实验教学中存在的问题,提出在实验教学中引入Multisim进行辅助分析与设计。利用Multisim对高频电路中的典型电路振幅调制及解调、丙类功率放大器进行了仿真研究,其各项结果与理论一致,且可以很方便地改变元件或电路中参数,观察不同条件下电路的工作情况。将虚拟实验和传统实验有机结合起来,能更好地提高学生的动手能力和探索精神。
The Multisim simulation tool is introduced in experimental teaching for assisted analysis and design to solve the problems existed in traditional high frequency circuit experiment. The class-C high-frequency resonance power amplifier, amplitude modulation and demodulation are simulated by Multisim, which are typical circuits of high frequency circuit. All of the results are identical with the theory, and it is convenient to change the parameters and component of circuit, as well as observe the working flow of circuit in different conditions. The virtual experiment is integrated with traditional experiment, what can improve the studentsr operational and groping ability.
