地震数据采集系统精度分析

Accuracy Analysis for Seismic Data Acquisition System

近年来 ,地震勘探领域普遍关心∑—△ 2 4位ADC能否取代传统的瞬时浮点放大器 (IFP)加ADC结构的问题。通过大量的仿真计算 ,从理论上给出了解答 ,IFP加ADC结构是理想的数据采集系统结构。随着电子技术的发展 。

In recent years,the wide concern in the field of seismic prospecting has been whether ADC of -△24 can replace the conventional IFP with ADC structure.A theoretical solution to this problem is found by much simulated calculation.It is discovered that IFP with ADC structure is ideal for DAS and that IFP will certainly play its due role with the development of electronic technology.
