The study of the characteristics of the receiver of professional communication: methodological instructions for laboratory work on the course "Transmitters" by A. M. Brigidina is a unique tool that will become an indispensable assistant for students and specialists in the field of communications and radio engineering. In this paper, the author invites the reader to immerse himself in the world of technologies that are behind modern information transmission systems, and explores in detail the characteristics of receivers used in professional communication. From the first pages of the book, Brigidin sets the tone that combines a scientific approach and a practical focus. It not only describes the theoretical aspects of the work of the receivers, but also invites readers to actively participate in laboratory research, which makes the learning process more exciting and interactive. In this context, the book will be of interest not only to students of technical specialties, but also to practicing engineers who want to update their knowledge or master new technologies. The topics raised in the book cover a wide range of issues related to the principles of the receivers, their characteristics and testing methods. Brigidin emphasizes the importance of understanding these aspects for the successful design and operation of communication systems. The reader will be able to learn about the different types of receivers, their features and application in real conditions, which makes the material especially relevant for future communication specialists. The book "Study of characteristics of the receiver of professional communication" is distinguished not only by its
