摘要
介绍多量程自动选通地震模拟遥测系统的工作原理及使用结果。采用此方案，综合动态范围可扩大到９０－１００ｄＢ，用事件判别触发发射的办法，维持功耗可小于１ｗ。
To overcome the insufficiency of seismic analog radiotelemetering system which is popularly used in our country,a multirange autoselected seismic telemetry system as well as its principle and observational results are described in this paper. The overall dynamic range will be enlarged to 90-100dB and the standby power consumption will be less then lw, when this scheme is used. The accuracy of digital telemetry is also discussed in this paper.
