| 摘 要： | 针对模拟电路中设计性实验教学的特点,以带音调控制的音响放大器的设计性实验为例,依据模拟电子技术的相关理论,利用Multisim 10设计实验电路并进行仿真验证,得到各部分输出电压波形及幅频特性,再进行实物安装与调试,然后将实验数据与理论值对比,找出出现误差的根本原因并提出了实验室较易实现的改进方法,使得实验的正确性得到了保证.

| Abstract: | According to characteristics of the designing experiment teaching with analog cir-cuits,this article takes the designing experiment of the audio amplifier with tone controling for exam-ple,based on the theory of analog electronics technology,designs and simulates the circuit by Mul-tisim 10.The output voltage and frequency charateristics of each part are obtained.After installation and debugging,the experimental data and the theoretical value are compared,which benefit to find out the root causes of the difference.Furthermore,the improvement method which could realize easily in the laboratory is proposed,and it ensures the correctness of this experiment. |
