This book presents the maintenance of radio equipment and the principles of operation of various radio receiving devices in civil aviation. The main feature of this book is the fact that it covers almost all types of radio receivers currently used in radar, communication and navigation equipment of civil aviation. Special attention is paid to ensuring the sensitivity of the receiver, as well as noise suppression under various conditions. A detailed description of the set of methods for receiving signals, especially in the case of frequency telegraphy is presented. This book provides a detailed description of specific methods of signal processing with frequency modulation-the so-called threshold-lowering reception methods based on reducing the bandwidth to the detector part of the private reception path in combination with the principle of negative feedback. The material presented in this book follows a logical sequence with a large amount of illustrations.
