%X With respect to high speed acquisition system,the band of power line interference is extreme narrow.In the design of power line interference filter with traditional IIR and FIR methods,there is a need of a high order filter of favorable attenuation characteristics,it is hard for hardware and software to realize.Considering the wide frequency bandwidth of seismic electromagnetic radiation pulse,high sampling rate in the observation system and the characteristic of TMS320C6416,an improved algorithm of frequen...
