利用M ultisim10．1软件对压控电压源二阶低通滤波器进行仿真分析，通过选择不同信号源观察输入、输出波形的相位关系和幅值关系，比较输出、输入波形幅值比是否等于通带电压放大倍数；调节负反馈电阻大小，观察品质因素变化对滤波器幅频特性和相频特性的影响，得到的仿真的结果与实际理论分析基本一致。仿真结果表明，将M ultisim10．1合理地引入到模拟电子线路实验教学中，能将一些高深、抽象的电子电路的理论教学变得具体和生动，有利于学生对电路的认知，提高电子线路理论课的教学效果和教学质量。

The two-order low pass active filter circuit of voltage controlled voltage source has been analyzed and simulated by Multisim10 .1 software ,observed the phase-frequency and amplitude-frequency of output and input waveform via choosing different signal sources ,the output and input waveform amplitude ratio compared is equal to the pass band voltage amplification or not ;when by adjusting negative feedback resistance ,the influence of phase-frequency and amplitude-frequency characteristics as quality factors changing can be observed .The simulation results are consistent with the practical theory .It shows that reasonably introducing Multisim10 .1 simulation technology could make some abstract and advanced theoretical teaching become concretely and lively ,thus it is suitable for cultivating students’ cognitive view of circuit ,further can improve teaching effect and teaching quality of the Electronic Circuit Theory couse .
