摘要
通过选择递归滤波器的最佳采样间隔,并配以软件筛选法,使该滤波器能滤掉50Hz的整数倍系列的干扰信号(1～7倍)。在寻求测试曲线的平衡点方面采用了窗口收缩法,使平衡点不易漏掉。提供了该法的程序框图。
By selecting the optimum sampling interval of recursive filter and using the software scleening method, this filter can filter the series of interference frequency signals which frequencies are the integer times of 50 Hz(times: from one to seven). In the ease of seeking the balance point in the testing curve, the balance point is not easy to be missed because the method of window contraction is used. The program flow chat of this method is presented in this paper.
