Collection of works by an outstanding Russian scientist and engineer B. A. Kotelnikov prepared for the 100th anniversary of his birth. The fifth volume, which completes the publication of the Works and is timed to the 10th anniversary of his death, included the 2nd part of the classic two-volume textbook "Fundamentals of Radio Engineering", written in conjunction with A.

Published in 1950. 1st part (linear radio engineering) and in 1954. The second part (non-linear radio engineering) was an encyclopedia of engineering theoretical knowledge on radio engineering of that time. According to this textbook, many generations of students of technical universities of both the USSR and other countries studied. The unique structure of the two-volume book, the method of presenting the material, especially the fundamental sections of the theory, makes it interesting for the current generation of students, graduate students, teachers and engineers, as well as for everyone who is interested in the history of the formation of science and technology in our country. ;Griff:Adopted by the Ministry of Higher Education of the USSR as a textbook for electrical engineering universities and faculties
