摘　　要：通过Multisim 10.1软件对静态工作点稳定电路的频率响应进行了仿真,观察到了放大电路幅频特性波特图的变化规律,采用波特仪分析了耦合电容或旁路电容的大小变化引起下限截止频率的变化和发射极电阻的变化引起上限截止频率的变化,得出了虚拟仿真结果与实际理论计算相吻合。通过实例验证了,将Multisim 10.1仿真软件合理地引入电子电路实践教学后,可使电子电路理论教学变得更具体,有利于电子电路课程的教学质量提高。Frequency response of the quiescent point stabilizing circuit was simulated with the software Multisim 10.1. The variation law of the amplitude-frequency characteristics approximate Bode plot of the amplifier circuit was obtained by observa-tion. By the Bode meter,the lower cut-off frequency variation caused by change of the coupling capacity or shunt capacity and the upper cut-off frequency variation caused by change of emitter resistance are analyzed. The conclusion that the simulation re-sult is in accordance with theoretical arithmetic result is achieved. The actual exampleverification shows the reasonable utiliza-tion of Multisim 10.1 in the experimental teaching of electronic circuit can make abstract theoretical teaching become more con-cretely and be propitious to improvement of teaching quality of electronic circuit.
