Fundamentals of Radio – Izyumov, Linde

In this post, we will see the book Fundamentals Of Radio by N. Izyumov and D, Linde.

About the book

These days radio engineering has become a very important branch of science solving a large number of problems associated with economic, technological and cultural progress. Every year, it finds ever increasing application and the number of people using radio equipment constantly grows. Many of these people have only rudimentary or no knowledge of radio engineering, although modern radio equipment is often so complicated that its effective use is impossible without some training.

The wide sphere of radio application in different branches of science and technology, as well as its close connexion with art and sport has also created a great number of radio amateurs in all countries. Some build radio receivers, tape recorders and TV sets, others design radio controlled models, short and ultra shortwave transmitters or equipment for a fascinating game called “hunting for a fox”, etc.

All this increases the interest in radio engineering knowledge on the part of an ever growing number of people. The study of radio is, however, made more difficult for the majority of readers as it is usually explained with the use of higher mathematics. On the other hand, when higher mathematics is not used, many important problems are often oversimplified and treated without sufficient explanation and demonstration. Moreover radio engineering is a coherent science in which everything is interrelated and interdependent; therefore lack of understanding of fundamental phenomena and laws prevents the reader from fully understanding further problems. It is far from clear what one should understand under the name of “radio engineering,’ and its fundamentals since this branch has been extended, diversified and become interwoven with many other branches of science and technology. Under “radio engineering” proper one usually understands the use of electromagnetic radiation for the obtaining of information from a distant source. This is effected through the use of a transmitting (radiating) device and a receiving device provided conditions for propagation of radio waves are favourable. In accordance with this, the book describes the operating principles of radio transmitters, radio receivers and radiating devices, as well as radio wave propagation. It goes without saying that one book cannot exhaustively deal with all the varieties of existing radio circuits and devices; therefore, we concentrate our attention only on the most important and representative types.


The book was translated from Russian by A. Ulyanov and was published by Mir in 1976.
