计算机仿真在高频电子线路教学中的应用

Application of Computer Simulation in Teaching of High Frequency Electric Technology

针对传统高频电子线路教学中存在的问题,提出在教学中引入计算仿真进行辅助分析与设计.阐述了Multisim的主要功能与特点,并利用Multisim对高频电路中的典型电路单调谐回路谐振放大器、环形调幅器进行了仿真,各项结果与理论推导相符.形象、生动的演示达到提高学生学习兴趣的效果.

Aiming at the problems in traditional teaching of high frequency electric technology, it is presented that multisim should be applied to the high frequency electric technology. The function and characteristics of EDA software Multisim2001 were introduced. The high frequency single tuned amplifier amplitude modulation, which is a typical circuit of high frequency electric technology, is simulated by Muhisim2001. All results are identical with theoretic. The visual and dramatic demonstration can promote the student＇s study interest.
