The development of modern systems of measurement, control, management and diagnostics is characterized by an increase in requirements for quality indicators, an increase in functionality, an increase in the complexity of research and design tasks in their creation. As a rule, the basis for the functioning of these systems are the methods and means of processing experimental data and computer implementation of mathematical models. In many practically important tasks, prompt assessment of the processes and phenomena under testimony of measuring instruments is of paramount importance. Similar tasks are known in practice as signal recovery tasksThe use of computer equipment for signal recovery makes it possible to use low-cost primary measuring transducers with low resolution in systems of measurement and control. The efficiency of the use of computing devices in measurement and control systems is primarily due to the low cost of their development in comparison with the improvement of the physical design of certain elements of these systems. Moreover, in some cases, such a possibility is limited not just by physical boundaries, but more so by economic factors.The development of methods of operational processing of information is characterized by an increase in the proportion of inverted tasks in the total list of solved problems by systems of this class. This implies that in principle, all the problems of mathematical modeling can be divided into two groups: direct problems, i.e. problems of analysis, when the known causes of certain processes and one has to find the consequences, and inverse problems, when the consequences are by physical boundaries and one has to find the reasons. One of the most important tasks of signal recovery is the task of structural correction of the characteristics of dynamic systems, which is constructing and using in the conversion channel or circuit of the system such blocks, which, due to their specially formed dynamic properties, transform in a necessary way the general dynamic properties of the system.
