摘要
在高分辨率勘探中,为提高高频小信号的分辨能力,对∑一△24位A/D转换器的地震仪器该不该加大陡度的模拟低切滤波器,这一直是个很有争议的问题,本文作者在近一年的工作中,对近十种不同型号的现代遥测地震仪器的特性进行了详细的定量测试和分析,得出了相应的结论。
Do seismic instruments with ∑-△ 24 bit A/D converter need any high slope analog low-cut filter to enhance the resolution of weak signal of high frequency in high-resolution prospecting or not? It's a con-tentious question in nowadays. After made a detailed quantification test and analysis on over 10 serials of currently telemetry seismic instruments, the authors of this paper reach their conclusion.
