ANALYSIS ON THE BACKGROUND NOISE AT THE SUB-STATIONS IN SHANXI DIGITAL TELEMETERED SEISMIC NETWORK

摘要: 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。

Abstract: 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 stationsis accordant with the specification of digital seismic observa-tion.
