Paperback. Condition: New. Print on Demand. This book offers a clear and simplified description of the basic principles underlying wireless telegraphy. The author first explores the concepts of electrostatics, electrodynamics, and magnetism, with a special focus on static induction and the functions of condensers. These principles are then used to explain the operations of common wireless telegraph apparatus, such as induction coils, transmitters, and wavemeters. Finally, the book concludes with a section on aerials, exploring the size, height, and distribution of potential and current along them. The author writes in an accessible tone, avoiding complex jargon and using straightforward analogies from the mechanical world to illustrate key concepts in a way that makes them easy to grasp. By breaking down complex electronic theory and concepts into manageable, easy-to-understand components, the author has deftly illuminated the foundational principles of wireless telegraphy. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.…
