Why 24-bit seismic acquisition system has no low -cut filter.

Ye Xieliang  
This article gives a complete commentary on the relationship between system dynamic range of teleme-try seismic acquisition system and resolution of low -amplitude seismic reflection signal according to spec-trum analysis examples. It also describes the influence on the system with low -cut filter-particularlythe influence of the analog low-cut filter and put attention to explain why 24 -bit system with 120 dB dy-namic range has no any low -cut filter.
