摘要
结合虚拟仪器的强大软件计算和图形显示功能,提出基于虚拟仪器结构,将非线性微分方程数值解法产生的不含噪声的混沌信号,通过数据采集卡D/A输出不含噪声的模拟量的混沌信号;利用数据采集卡的A/D将上述模拟量的混沌信号采样,基于“相关平面”的原理,设计出了混沌和噪声辨识仪。
Virtual instrument configuration is convenient to realize chaos' generation and identification provided due to its strong software computing and figure display function. Numeric chaotic signal without noise is produced through typical nonlinear differential equation using numerical value solution, and then analog chaotic signal without noise can be gained from the conversion of numeric chaotic signal using data acquisition card D/A. The virtual instrument for recognizing chaos and noise is designed based on correlation plane.
