CMG-3ESPC宽频带地震计稳态标定和传递函数构建

Stead state calibrating and transfer function constructing of broadband seismograph CMG-3ESPC

介绍了利用稳态正弦标定测定CMG-3ESPC宽频带地震计幅频特性的方法,换算仪器零、极点参数,重新计算了传递函数归一化因子并对测震系统的幅频特性进行了验证。

The method to use the stead state sine wave to calibrate the amplitude frequency response characteristic of broadband seismograph CMG-3ESPC and the conversion parameters of seismograph at zero and top points and the transfer function are described. The calculati6n of transfer function is made. The amplitude frequency response characteristic of broadband seismograph system CMG-3ESPC is tested.
