Verification of frequency characteristics of load devices declared by the manufacturer

Abstract

The aim of the work was to clarify the possibility of determining the frequency characteristics of load devices according to the parameters of transients, the rate of rise of the leading edge, its duration, the presence or absence of overshoot, the form of the transient process. The main objective of the study was to determine the load parameters required to perform the calculation. To confirm this hypothesis about the influence of the selected parameters, the method of physical experiment was used. The specification of indicators for operational parameters may be relevant when organizing the input control of incoming purchased products for various applied tasks. The improvement of input control algorithms, the implementation of time characteristics checks instead of frequency ones will confirm the compliance of the characteristics declared by the manufacturer or supplier of this equipment and provide the possibility of identifying the internal structure of devices to ensure their compatibility with other equipment used in production, as well as expand the technological capabilities of enterprises. The indicated problem seems promising for a number of organizations operating complex electronic equipment, as well as for domestic manufacturers of electronic devices. The relevance of the study also lies in reducing the amount required for the verification process of equipment by increasing the computational load. In addition, dynamic identification by transient parameters increases the speed of verification.
