| Abstract: | 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. |
