Communication Theory and Radiophysics (on the Teaching of the Theory of Communication and Information at the Department of Physics)

The paper discusses the improvement of the methods of teaching the courses of the theory of communication and information at Saratov State University by introducing additional sections on the analysis of radiophysical processes in various devices of communication systems. We propose the electrodynamical analysis of wave processes in a fiber optic line, features of the use of new CMOS devices for signal conversion in communication systems and selected schematic solutions.
