The tutorial contains tasks for all sections of the course of the same name. It contains task conditions, solution examples, guidelines and answers. When working with the manual, it is recommended to use the textbook by S. Baskakov "Radio circuits and signals" (M,: High. shk. 2000). Tasks on wavelet analysis of signals and methods for evaluating information characteristics of a radio channel have been added to the second edition. Tasks related to computer analysis of circuits and signals using MathCAD and Electronics Workbench software products are proposed.
