山西数字遥测地震台网十五勘选子台台址地动噪声分析

Analysis on the background noise at the sub-stations in Shanxi digital telemetered seismic network

对山西数字遥测台网"十五"勘选的19个子台台址背景噪声进行分析和计算,得出了各台址背景噪声地动速度均方根值(RMS值)、有效测量动态范围、噪声信号功率谱。结果表明,各台址背景噪声水平符合数字地震观测技术规范要求。

RMS (root-mean-square) values of ground motion noises, effective dynamic ranges and noise power spectrums of 19 stations selected by 'the tenth-five-year project' are calculated and analyzed. The results show that the background noise level of all the 19 stations is accordant with the specification of digital seismic observation.
