本书是一本六十四页的小册子,是电力系统的工程技术人员可贵的参考书,篇幅虽小,但却能在其中把输电线上的载波通讯所应说明的各种问题,简单扼要地叙述出来,是一本值得介绍的良好著作。全书共分五章,第一章叙述了输电线路载波通讯在苏联的发展简史。第二章叙述了载波通讯技术的基本原理,其中讲到幅度调制和频率调制的简单原理,讯号在空间和在导线上的衰减情
This book is a 64-page booklet. It is a valuable reference book for engineers and technicians of the power system. Although the space is small, it can simplify the problems that should be explained in the carrier communication on the transmission lines. Narratively speaking, it is a good book worth introducing. The book is divided into five chapters. The first chapter describes the brief history of the development of carrier communication of transmission lines in the Soviet Union. The second chapter describes the basic principles of carrier communication technology, which talks about the simple principle of amplitude modulation and frequency modulation, and the attenuation of signals in space and on wires.
