摘要

本文提出了一种周期性加载电话线的理论,该理论可以显著降低基带电话信号传输中的衰减,并对其进行了实验验证。这种所谓的Pupin负载是通过使用沿线路均匀分布的环形离散电感线圈来实现的。此外,为了进一步说明Pupinpsilas线圈内含物对线路传输特性和带宽的影响,本文还采用了Pupinpsilas线圈内含物对线路传输特性和带宽的现代全波矩阵方法。为此,引入了所谓的Heaviside准则实现因子,并与空载线和等效均匀线特性进行了比较。

Invention of Pupin’s periodically distributed inductance coils to allow for long-distance telephone transmission
Pupinpsilas theory of periodically loaded telephone lines, allowing for significant reduction of attenuation within the baseband telephone signal transmission, and its experimental verification are presented in this paper. Such so-called Pupin loading was achieved by the use of discrete inductance coils of toroidal form equally distributed along the line. In addition, a modern full wave matrix approach of such Pupinized transmission line is used in order to further illustrate the effects of Pupinpsilas coils inclusion on line transmission characteristics and bandwidth. For that purposes, so-called Heaviside criterion fulfilment factor is introduced and comparison with unloaded line and equivalent uniform line characteristics is presented.
