本文给出了一种确定加权滤波的权序列的程序。首先对噪声污染的量测序列用快速傅氏变换(FFT)方法作频谱分析,确定有用信号的截止频率,然后用哈明时窗函数确定滤波因子,即加权滤波的权序列。用该程序可以设计出与加权平均形式相同的在线数字滤波器,所加的权是根据噪声的性质设计的归一化的滤波因子。 This paper presents a program to determine the weighted sequence of weighting filters. First of all, the measurement sequence of noise pollution is analyzed by Fast Fourier Transform (FFT) method to determine the cut-off frequency of the useful signal, then the Hamming time-window function is used to determine the filter factor, that is, the weight sequence of weighted filtering. Using this program, an on-line digital filter of the same form as the weighted average can be designed and the weights added are normalized filter factors designed according to the nature of the noise.
