摘要
从理论上讨论了几种数字滤波器的工作原理及实现方法。着重分析了经典滤波器、统计滤波器和相关检测的工作原理，并给出了各滤波器系统的分析方法和传递函数，简化了数字滤波器的实现过程。为寻找到适合于地震数据传输的滤波方法做出了有益的探索。
The operation principle and realization method of several numerical filters are discussed in theory The operation principles of the classic and statistical filters, and correlative detection are emphatically analysed, and the analysis methods of various filter systems and transfer function are given, and the realization process of numerial filter is simplified to search adaptive filteration method of seismic data transmission
