摘要
为了帮助学生对电子电路的本质有更直观的认识,在模拟电子电路的教学中引入了Multisim 10仿真软件。实验利用该软件对三极管单级放大电路进行仿真分析,结果表明,电路元件参数的改变直接影响电路的静态工作点,动态输出也因此产生变化。该实验揭示了静态工作点的重要性,与理论分析的结果一致。利用仿真软件分析电子电路,结果形象直观,既起到辅助课堂教学的作用,也激发了学生对电子电路的学习兴趣。
MultisimlO software is introduced into the teaching of analog electronic circuit to help students to understand its essence intuitively. The simulation analysis for single stage amplifying circuit of bipolar junction transistor （BJT） was carried out by using MultisimlO software. The result proves that quiescent operating point will be changed if circuit component parameters is changed, and the result of dynamic output will be changed at the same time. This reveals the importance of quiescent operating point. These results are consistent with those of theoretical analysis. The result using simulation software to analyze electronic cir- euit is visual. This not only achieves the objective of auxiliary classroom teaching, but also stimulates students＇ interest in elec- tronic circuit.
