If you use inductors and transformers with magnetic cores, you need this book. By the late, legendary designer and amateur radio operator Doug DeMaw, W1FB. The only book that emphasizes practical aspects of magnetic cores, you need this book. By the late, legendary designer and amateur radio operator Doug DeMaw, W1FB. The only book that emphasizes practical aspects of magnetic core materials from low frequencies through UHF. In-depth understanding of basic theory, many practical circuit examples that use toroids, rods, and pot cores made of ferrite and powdered iron. All circuits were proven in the lab by the author. Learn proper core selection versus operating frequency and more!
