摘要
介绍了山西数字测震台网EDAS-24IP+BBVS型数字地震仪传递函数的特征和测定方法,对地震仪阶跃标定及正弦标定计算分析,得出台站工作状态、地震计周期、阻尼、主零极点参数的变化情况;并对数字地震仪的频带范围、通频带的平坦程度、三分向幅频响应的一致性进行了讨论和分析。认为台网的系统特性是稳定和可靠的。
Characteristic and measurement method of transfer function of EDAS-24IP ＋ BBVS digital seismograph in Shanxi Digital Seismic Network are introduced. Through calculation and analysis on step and sine calibrations, variations of working state of station, period of seismograph, damping and parameters of dominating zero and pole point are figured out. Frequency band range, flat extent of transmission bands and consistency of three-component amplitude-frequency response of digital seismograph are discussed and analyzed. It is concluded that EDAS-24IP ＋ BBVS digital seismographs in the network are stable and reliable.
