| Abstract: | The broadband chaotic signal has good related characteristics,low intercept probability and high confidentiality etc, The paper introduces a kind of chaotic signal circuit-Colpitts oscillating circuit, and the improved circuit based on chaotic Colpitts oscillating circuit. It analyzes performance of two circuits through simulation, the results show that the improvement of Colpitts oscillating circuit is feasible, fre- quency spectrum of Third-order Colpitts oscillating circuit is relatively concentrated, and the related pro- perties is bad, it is used for telecom equipment, information technology, etc. And fourth-order Colpitts oscillating circuit generates higher frequencies and wider bandwidth of chaotic signal, it is suitable for com- munication and radar waveform. |
