摘要/Abstract

摘要： 将现代网络综合设计的理论和方法——插入衰减综合法从电压传递函数K_v(s)推广到电流传递函数K_I(s)、转移阻抗函数Z_m(s)和转移导纳函数G_m(s),从而使插入衰减综合法适用于一切传递函数.并获得如下重要结论:现有的针对K_v(s)、R₁=R₂=1Ω(归一化阻抗)所制作的各种滤波器设计图表均可用来设计与K_v(s)具有相同传递特性的K_I(s)、Z_m(s)、G_m(s)滤波器。

关键词: 网络综合, 滤波器设计, 插入衰减综合法

Abstract: In this paper the insertion loss synthesis for voltage transmission functions K_v(s) is extended to synthesis for current transmission functions K_I(s), transfer admittance functions G_m(s) and transfer inpedance functions Z_m(s). Another important result is:If there are K_I(s)=G_m(s)=Z_m(s)=K_v(s), and R₁=R₂=1Ω, then extant filter design digital forms for K_v(s) can be used to design filters for K_I(s), G_m(s) and Z_m(s).

Key words: insertion loss synthesis, network synthesis, filter design
