摘要
本文利用虚拟仪器软件LabWindows/CVI设计出一个基于Logist方程的混沌白噪声发生器,进而由LabWindows/ CVI驱动数据采集卡输出混沌白噪声信号,最后利用系统的自检功能评估该虚拟混沌白噪声发生器所产生的白噪声信号的性能。与传统的白噪声信号发生器相比,本文设计的虚拟白噪声发生器具有参数调节方便、易实现、可靠度高等优点。
LabWindows/CVI is used to design a chaotic white noise generator based on logist equation in this paper. Then, chaotic white noise signal is generated by LabWindows/CVI driving data acquisition. Finally, this system can evaluate the capabilities of the white noise which is produced by this virtual chaotic white noise generator. Comparing with traditional white noise generator, this virtual chaotic white noise generator has some properties, which including convenient parameter changing, easy gaining, high accuracy, and so on.
