Background. Information-measuring and management systems use parametric primary converters of information (PPC). A large number of variants of composition and structure of multi-element two-terminal electrical circuits (TEC), being electrical models of PPC, causes a necessity to use multiple types of secondary converters (SC), which increases development time and cost of systems. The purpose of the research is to develop a universal SC, capable of converting output signals of all types of PPC into code.
Materials and methods. The research was performed using the methods of modeling through synthesis of electrical, structural and mathematical models of sources and converters of information.
Results. The authors have synthesized a universal SC model in the form of a TEC with unchanged topology. Harmonic voltage was defined as the only form of energy impact on the PPC by the SC at conversion of a passive electrical value into an active one. The authors have designed a universal SC conversion process structure as a phase of PPC informative value measurement.
Conclusions. The article suggests a structural model of simultaneous conversion of analog information on immittance components of primary parametric converters into code. The model can serve as a basis for development of universal secondary converters of parametric information from primary converters.
