| 摘 要： | 24位地震数据采集器中的数据处理过程是:地震计将感应到的地面运动信号转换成电压值输出给采集器,采集器将模拟电压信号进行滤波放大,再进行A/D转换成512KSPS的1位数据码流,该码流经DSP的两段滤波后得到COUNT值,DSP从RAM中取出COUNT值归一化后打包输出。

| Abstract: | Data processing of 24 bit earthquake data acquisition device is as follows:seismometer convert the ground motion signal sensed to voltage,and output to earthquake data acquisition device.The acquisition device amplifies the anolog signal,and convert the signal to 1 bit 512K digital code stream with A/D,after DSP filtering,COUNT value is got from the stream.DSP normalize COUNT value from RAM,and then package it to output. |

| Keywords: | 24 bit earthquake data acquisition device 512K data stream DSP filter COUNT value |
