摘　　要：介绍了一种新的方法实现对Colpitts混沌信号的产生,该系统是基于虚拟仪器平台并结合MATLAB计算模块实现对Colpitts混沌信号的产生,同时对混沌信号的自相关和功率谱进行分析。并通过USB-6009采集模块外扩高速DAC(数模转换器)芯片AD5405实现对Colpitts混沌信号的单通道输出。系统可根据用户的需求调节参数,实现不同频率混沌信号的产生。结果证明,该发生器结构简单,操作方便,运行稳定可靠,有一定参考和实用价值。We introduces a new method that can achieve the generation of Colpitts chaotic signal The system is based on virtual instrument platform and combined with MATLAB calculation to achieve the generation of Colpitts chaotic signal and make analyse with autocorrelation and power spectrum at the same time. Signal channel output of chaotic signal was realized through USB-6009 acquisition module extending DA5405 high-speed DAC （ Digital-to-Analog Converter） chip. This system can adjust parameters according to users demand to achieve different frequency chaotic signal generation. The results demonstrate that the generator has simple structure, convenient operation, stable and reliable running,so it has some reference and practical value.
