摘    要:重点介绍了在变换域直接进行数值最优逼近、霍氏等价式的提取、网络参数的构建以及用“极点消去法”求解网络元件等与分波器的高精度计算机辅助设计(CAD)有关的一系列重要问题。实践证明:用本文给出的方法不仅设计精度高、速度快,而且非常灵活。虽然本文所述的方法主要是用来设计各种分波器的,但它也完全可用于一般低通、高通、带通及带阻滤波器的设计。

关 键 词:分滤波器  变量变换  最优数值逼近  极点消去法  计算机辅助设计

Abstract:The emphasis is put on the introduction of a series of important problems related to computer aided design(CAD)of filters in transform area, including optimal numerical approximation,extraction of Hurwitz's equivalent polynomial, construction of network parameters,derivation of network elements by using "pole-removed method" etc. Design practices prove this method given by this paper not only is of higher accuracy and speed,but also is very flexible. The methods given are suitable for the design of general high-pass filter,low-pass filter,band-pass and band-resistant filter, although they are to design the various kinds of filter-dividers.
Keywords:filter-divider  variables transform  optimal numerical approximation  pole-removed method  CAD
