摘要
本文提出数字滤波器的结构无源T-级联实现的统一方法,使反对称和非对称滤波器的实数正则实现问题得以解决,并使波数字环形滤波器和波数字格形滤波器可在Z-域统一实现,已有的各种T-级联结构无源数字滤波器均可由本文方法得到。
In the paper, we present the unified approach for realization of T-cascade structurally passive digital filters The approach is first to constructed the transfer matrix of a lossless two-pairs by the transfer function of a digital filter, then derive the structurally passive realization by decomposing the transter matrix. The existing approach for the realization of T-cascade structurally passive digital fil.ers all can be derived by the approach in the paper The wave digital lattice filters and wave digital circular filters can be realized in Z-domain unified by our approach. We resolve the problem of real canonic structurally passive realization of antimetric and unsymmetric digital filters by presenting real antimetric lossless two-pairs and unsymmetric lossless two-pairs.
