Principles and Practice of Wireless Transmission

THE author gives a popular account of the principles underlying the art of radio transmission and radio reception. He confines himself, however, closely to the scientific theory of the subject and does not give loose analogies. He states that mathematical treatment is “apt to irritate “the non-technical reader, but nevertheless he introduces the main formulae. No attempt is made to prove the formulas, but their practical use is explained with sufficient clearness to help the amateur. In no branch of electrical science is the theory of electrons more helpful than in radio communication. Hence although the author starts with discussing the electrifications produced by rubbing a stick of sealing-wax with a piece of fur, yet the phenomenon is pictured as giving or depriving atoms of the materials of their electrons.Principles and Practice of Wireless Transmission.By G.
