| 摘 要： | 针对某些雷达、通信等系统在应用中对混沌信号频域带宽的要求,设计了一种基于考毕兹振荡器电路的宽带混沌信号发生器。该混沌信号产生电路由考毕兹振荡器为基本谐振电路、级联若干容阻串并联单元的选频网络构成,混沌信号的上下限频率分别由基本谐振电路和第一节容阻串并联网络参数决定,通带频谱的平坦性受其他级联选频网络影响。根据初步分析和仿真试验,该混沌电路组成结构简单,能够产生带宽超过60MHz较为平坦的宽带混沌信号。

| Abstract: | In practical applications of some radar or communication system,the frequency domain bandwidth of chaotic signals is often required.A wide-band chaotic signal generator based on Colpitts oscillator is introduced,which is composed by Colpitts oscillator and some RLC circuit network.The spectrum width of the chaotic signal which is generated in the given circuit is decided by the circuit parameters.By simulating and analyzing of the chaotic circuit,some flat spectrum of chaotic signal can be generated whose s... |
