【Abstract】 The task for selection and construction of Yingshan digital seismostation comes from sub-programs of Hubei Provincial earthquake background field exploration project,which is one of newly-built unattended digital seismic stations in Hubei province during the Eleventh Five-Year period.By analyzing and calculating the background noise of Yingshan digital seismostation,we got the root-mean-square(RMS) value of the ground pulsation speed,the dynamic range of observation and the power spectrum of the noise signal about the background noise of station.The result shows that the background noise level of the station satisfy basically the normative requirement of the digital seismic observation technique.更多还原
