Аннотация: This article discusses the development of twochannel sensitive sensors for recording seismic vibrations. The influence of the instability of the element base in the implementation of sensor data using analog amplifiers and filters is considered. It is shown that the effect of this instability can lead to the formation of measuremenПоказать полностьюt errors. Even a change in the cutoff frequency of several hertz leads to the formation of an error of the order of 10-15%. The characteristics of digital filters that can be used in these sensors are given, which, using modern microcontrollers of the ARM architecture, will allow not only filtering in real time, but also perform mathematical processing of received signals.
