摘　　要：介绍了电路原理实验课的一个模块化、开放式的综合实验。在蔡氏电路的基础上，对部分功能模块进行了一定的改进，利用模拟电感代替真实电感，并在电感支路上增加RC并联结构，以此设计出性能相当稳定的混沌信号发生电路。通过简单电路和听音实验对混沌保密通信进行了原理上的研究。Considering the problem of information exchanging security, the feasibility of chaotic circuits is searched. Based on the original Chua circuit, this paper puts forward a modified Chua circuit with stimulated inductor and RC parallel structure and applies it in stimulated communication circuit. The results have not only successfully demonstrated chaotic secure communication, but also made it clear that the modified circuit is more robust as to set a very important foundation for chaotic synchronization communication.

关 键 词：混沌 蔡氏电路 模拟电感 保密通信
