A digital seismometric channel in the state space

© Nesterenko S.D.

In the modern seismometry the analog electrical signal from an output of a seismometer is digitized and recorded in a digital form on the information carriers. The article proposes to use the experience of the development of an electronic measurement technology of direct digitizing of the relative displacement of an inertial mass, and a digital-to-analog converter in a feedback circuit. The methods of the analysis and synthesizing of similar systems are based on a method of the mathematical description of the processes in a state space.
