| 摘 要： | 本文给出二阶跟踪—微分器的频率特性 ,此频率特性类似于二阶线性低通滤波器的频率特性 ,但具有线性系统所没有的优点 ,即通带内有较小的相移 ,且无谐振现象 .同时 ,文中指出频率特性与跟踪参数和正弦输入信号幅值之间的关系就是一个简单的“平移”

| Abstract: | In this paper, the frequency characteristics of Second-Order Tracking-Differentiator are presented. They are similar to those of second linear low-pass filter, but with much better properties. That is, TD has smaller phase-shift in passing band, and resonant phenomenon doesn′t occur. Meanwhile, it is showed that the relationships of frequency characteristics with tracking parameter and amplitude of sinusoidal input are just the simple ″parallel-shifting″. |
