Abstract

The article analyzes the type of energy-dynamic pulses in the space-time and frequency-spectral domains to improve the diagnostic process of digital standard replacement elementswith large integrated circuits and microprocessor-based large integrated circuits in their design.Creation of new and improvement of existing systems used to determine the technical condition of digital devices in complex conditions requires the development of new methods of diagnosis. This is due to the high complexity of radio-electronic equipment and the shortage of decision time when carrying out technical state control.In the scientific and technical literature on the development and operation of radio electronic equipment, the main attention is paid to the study of the possibility of minimizing the average recovery time and cost of means of diagnostics of the radio electronic equipment object.The main factor holding back the development of modern technical diagnosis systems is the lack of a methodological apparatus capable of significantly more effective use of developed diagnostic models to identify faulty logical elements. Application of the proposed scientific approaches to the processing of diagnostic information will allow: to determine in advance the elements whose characteristics are approaching critical; to determine the technical condition of radio electronic equipment in real time; to monitor the serviceability of elements of radio electronic equipment.It will also allow for more accurate processing of diagnostic parameter values, forecasting failure times of radio electronic components with a given reliability.This, in its turn, will lead to decrease of detection time of sudden failures of radio-electronic facilities and considerably reduce time spent on restoration of digital standard replacement elements of radio-electronic equipment, requirements to which are constantly growing in conditions of repulsion of the russian aggression by the Armed Forces of Ukraine.
