| 摘 要： | 介绍了一种开关电容式自动跟踪滤波器。这种跟踪滤波器以状态变量滤波器为基础，通过锁相倍频器和开关电容实现滤波器的中心频率与控制频率相等。该滤波器不仅能在跟踪滤波的同时放大同频信号，而且还具有处理速度快、整体结构简单等优点。此外，还给出了具体电路的参数和试验测试结果。

| Abstract: | An auto-tracking filter of switched capacitor is recommended.This tracking filter is based on state variable filter and make central frequency be equal to control frequency.And the filter not only is capable of magnifying the signal of the same frequency while filtering by tracking,but also has some merits,such as rapid management,simply whole structure and so on.In addition,parameter and test data of the specific circuit is presented. |
