The lowpassfilter (LPF) and the double second rank filter (DSF) are tested to reduce the mechanical oscillation of FSM.
讨论了低通滤波和双二阶网络滤波等几种可以减小倾斜反射镜机械谐振的方法。

This paper improved the harmonic current detection method based on UPF (unity power factor), using the slipped window integral to replace the LPF (lowpassfilter).
本文对基于单位功率因数的谐波电流检测方法进行了改进,用移动窗积分法取代检测中常用的低通滤波器。
