摘要
根据变数据窗滤波算法的特点，提出了几种适用于递推估计计算的非周期分量处理方法。并从频域和时域的角度对它们的滤波性能进行了分析比较。结果表明，指数拟合法具有较好的综合滤波性能。数字仿真结果证实了该方法的有效性。
This paper presents several D. C.rejection methods which are suitable tobe used in recursive estimator.These algorithms are analyzed and evaluated in both frequency domain and time domain. Resultsshow that the exponential function fitting method behaves best.The validity of the algorithm has also beenexamined by simulation tests.
