本文提出一种动态补偿数字滤波器(简记为D.F.,下同)的时域设计方法,D.F.以闭式形式给出。与现有资料中介绍的递归D.F.的时域设计法相比,本方法有如下几个特点:①没有解非线性超定方程组的困难;②可根据对D.F.所要求的各种时域动态特性来进行设计;③D.F.阶次的确定采用作者在文献中提出的适用性检验和快速跟踪检验;④在程序设计中考虑了滤波效果检验,在时域与频域都可以一目了然地看出滤波前后的动态特性。最后,本文给出了几个计算实例。
This paper presents a dynamic compensation of digital filters (abbreviated as D.F., the same below) the time domain design method, D.F. is given in closed form. Compared with the time-domain design method of recursive DF introduced in the existing data, this method has the following characteristics: (1) it is difficult to solve the system of non-linear overdetermined equations; (2) To determine the order of D.F using the author in the literature proposed applicability test and fast tracking test; ④ in the program design to consider the filter effect test, both in the time domain and frequency domain can be seen at a glance Dynamic characteristics before and after filtering. Finally, this paper gives several calculation examples.
