Inhaltsangabe

This book explores the mathematics of electric current propagation in telephone and telegraph conductors, helping engineers understand these phenomena, particularly from the perspective of hyperbolic functions. The author simplifies the theoretical treatment and provides arithmetic examples to enable readers to perform calculations. The book builds on the work of Heaviside, Pupin and others, detailing the theories of Pupin and Campbell on loaded cables. It also explores sinusoidal wave analysis, uncovering the qualities of sounds, such as loudness and vowel formation. The publication discusses the limitations of telephony and the methods for improving it, like the S.P. Thompson cable with inductive shunts. The text concludes with a chapter on electrical measurements and the determination of constants of cables. This book is valuable for telegraph and telephone engineers who seek to extend their knowledge in this field.

Excerpt from The Propagation of Electric Currents: In Telephone and Telegraph Conductors

This book is a reproduction, with some amplifications, of the notes prepared by the Author for two Courses of Postgraduate Lectures given by him before the University of London in the Pender Electrical Laboratory in 1910 and 1911, on the Propagation of Electric Currents in Telephone and Telegraph Conductors and on Electrical Measurements in connection with Telephonic and Telegraphic work. These Lectures had their origin in a request made to the University to provide a course of instruction for Telegraphic and Telephonic Engineers which should enable them to keep abreast of the most recent scientific and technical researches in these branches of Electrical Technology.

These Lectures were attended by a large class composed chiefly of practical Telegraphic and Telephonic Engineers and experts; and at the request of many who attended, and some who did not, the Author has written them out for publication.

As a considerable portion of the subject-matter included has not yet found its way into text-books, although distributed through various technical Journals and Proceedings, it seemed probable that a service would be rendered to Electrical Engineers generally if this material were collected and placed in an easily accessible form. Students of this subject are well aware of the great value of the pioneer work of Mr. Oliver Heaviside and of Prof. Pupin in laying the sound theoretical and practical foundations for improvements of great importance in telephony, and of the classical labours of Lord Kelvin in connection with submarine telegraphy. But the study of the writings of these originators makes a demand for mathematical knowledge which is generally beyond the attainments of the practical telegraphic and telephonic engineer.
