摘要
讨论了用开关电容滤波器(SCF)在宽频率范围内实现跟踪滤波的可行性。以一个 SCF 二阶节为例进行了理论分析和实验验证,在20Hz～20kHz 的频率范围内实现了自动跟踪滤波。
The realizability of tracking filter in wide frequency range with the switched capacitor filter (SCF) is discussed in this paper.As an example, the biquadratic SCF section is analysed theoretically and experimentally. The automatic tracking filtering from 20Hz to 20kHz is achieved.
