The statement of the "amplitude, phase, frequency" problem in radioelectronics

The physical interpretation of an error of amplitude, phase, and frequency definition over AS, including the special case of an arbitrary amplitude-phase modulation of a signal is considered. To realize great possibilities of the modern telecommunication systems it is necessary to obtain high reliability and quality of the transmitted messages. The tasks of optimal signal coding and processing are of special significance. The problem of correct definition of APF over CS agrees with a method simplifying researches of dynamic mode of operation of radioelectronic systems. The problem of APF is solved without any simulated build-up of CS.
