电信传输地震台网是为地震科学研究,及地震预报获取高质量的地震观测资料和地震前兆观测数据而建立的。将台网中各子台的信号传输汇集到记录、分析、处理中心,都是采用有大(?)载波话路传输、无线传输、无线→微波接力传输、无线→有线接力传输信道而进行的。众所周知,任何一种遥测信道,在传输有用信号的同时都会有各种干扰信号混入。这些干扰
Telecommunication transmission seismological network is established for scientific research of earthquake and obtaining high-quality seismic observation data and earthquake precursor observation data of earthquake prediction. The signal transmission from each sub-station in the network to the recording, analysis and processing center is carried out by using large-scale carrier voice transmission, wireless transmission, wireless → microwave relay transmission, wireless → wired relay transmission channel . As we all know, any kind of telemetry channel, the transmission of useful signals at the same time there will be a variety of interference signals mixed. These disturbances
