Abstract: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 measurement 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… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
