摘　　要：采用Multisim8软件创建负反馈放大电路,利用其虚拟仪表和仿真分析了功能测试和仿真分析负反馈对放大电路的影响,通过对串联负反馈放大电路的理论研究和利用Multisim8仿真软件对电路实际工作情况进行模拟,根据二者结果的对比,研究并提出了串联负反馈放大电路的Multisim电路仿真研究的方法。Multisim8仿真分析中图像清晰、现象直观、结果精确,是一种有效的辅助实验手段。A negative feedback amplification circuit is created using Multisim8, and the influence of negative feedback on the circuit are analyzed using the virtual instrument and powerful simulation function test. Simulation re- sults of the actual working condition of the circuit are compared with the theoretical ones, based on which a series of negative feedback amplifying circuit based on Multisim circuit simulation is put forward. Multisim8 simulation analy- sis offers clear image, visual phenomenon and precise result, and is a good auxiliary experimental means.
