MODELING OF ACOUSTO-ELECTRIC DEVICES AND SYSTEMS BASED ON A GENERALIZED SIGNAL CONVERTER CONNECTION

Abstract

The use of electronic systems is widespread in various metrology systems related to the monitoring of acoustic noise in urban or industrial environments. A method for analyzing equipments intended for acousticlocation and acoustic measuring devices and systems (DS) based on structural approximation is proposed. The method involves performing a structural approximation of the devices used based on the developed generalized circuit. In this particular instance, the analysis is conducted utilizing the apparatus of continuous piecewise-linear functions and transfer functions of the signal converter. Their utilization facilitates the investigation of devices (systems) of arbitrary structure, characterized by random nonlinear characteristics and a variety of inertial components such as blocks and units. The study of specific devices is based on the finite expressions of the transfer functions of a generalized signal converter connection. Several levels of disclosure of the converter connection are considered. Using the aforementioned methodology, it is feasible to synthesize acousto-electric devices (systems) at both the analytical and structural levels. As nonlinear differential equations of random order that describe the response of devices and systems can be reduced to linear equations of the first order in the general case, the inverse solution (synthesis) is not a complex task, both at the analytical and programmatic levels.
