摘要
本文导出了一种具有镜像对称形式特性的带通、带阻滤波器对,与具有同样指标的普通带通、带阻滤波器组相比较,可节省乘法器一半以上,并且结构简单,时延小.这种方法也适用于单独带通或带阻滤波器的设计.
This paper gives out a pair of band-pass and band-rejection filters which have mirror-symmetry character.Compare to ordi- nary filters having the same amplitude response,ours uses much less multipliers(coefficients),and has the simple structure.This method also is suited to the designing of only a band-pass(or band-rejection)filter.
