摘要
利用傅里叶分析法,把速度型宽频带数字地震记录变成台站人员所熟悉的长周期(763)、中长周期(SK)模拟常规地震记录,分析人员能在仿真后的记录波形图上识别震相和计算震级。
According to the Fourier analysis method, we have imitated long period(763), middle long period(SK) analog routine recording. which with the personnel in seismic station is very familiar, using broad band velocity type digital recording. Analyst can identify seismic phase and calculate magnitude on seismogram after imitation. This method provides a data processing method for seismic station to replace anolog recording with broad band digital data in future.
