| Abstract: | By analyzing and calculating the background noise of 11 substations of the digital remote earthquake station in Shanxi Province, we got the root-mean-square (RMS) of the ground pulsation speed, the dynamic range of observation and the power spectrum of the noise signal about the background noise of all stations. The result shows that the background noise levels of all stations satisfy basically the normative requirement of the digital remote earthquake observation technique. |
