Abstract
This paper analyzes the cause of frequency aliasing phenomenon when sampling the low frequency signal of geoelectricity, and brings forward the arithmetic of practical digital filtering; based upon the above, the anti-aliasing filter that makes use of cascade decimation was developed. The rationality of the design solution is validated through field spot signal collection.
