Title: Anti-aliasing Technique Using Cascade Decimation to Measure the Low Frequency Signal of Geoelectricity
Abstract: This paper analyzes the cause of frequency aliasing when sampling the low frequency signal of geoelectricity and brings forward the arithmetic of nume ric filter which has practical meaning. Based on this principle, the anti-alias ing filter which makes use of cascade decimation was designed.The rationality o f this scheme is validated through data collecting on the field.
