摘要
构造了一个新的混沌系统,对该系统的动力学特性进行了分析,并设计了实现该混沌系统的模拟电路,实验结果与仿真结果完全相符.为产生混沌伪随机数字信号,在此模拟混沌电路的基础上,设计了一个量化电路.EWB仿真表明,该量化电路确实能对模拟的混沌信号进行二值量化.
A novel chaotic system is constructed. Some dynamical properties of the system are analyzed, and an analogue circuit is designed for verifying the system. In circuit experiment,a good qualitative agreement between the numerical simulation and the experimental measurement is obtained. Furthermore, a quantization circuit is designed on the base of the analog circuit. In the EWB numerical simulation, the chaotic analog signal can be quantified into a binary sequence.
