Abstract

In this paper, for the purpose of the creation of a model of the vibroseismic monitoring process of a medium, the problem of the creation of a mathematical and an electrical model of a seismometer, as one of the components of a vibroseismic channel was set. The solution to the problem in question is obtained with the help of the method transforming the idealized schemes, the circuit theory analysis being a powerful modern means of analysis of electromechanical systems, to which, in particular, seismometers are referred. As a result of such a research, a model of a seismometer in the form of the principal electrical circuit was obtained. Such a form of representation of a seismometer has allowed, on the one hand, to correctly elaborate an input amplifier of a system with a minimum hardware noise and, on the other hand, it has allowed obtaining a transfer function of a correcting digital filter to widen a frequency band of received signals towards large periods.
