Two Signal Processing Methods of the Magnetotelluric Impedance Measurement

HUANG-FU Li-qun(Department of Electrical Engineering,Huaiyin Institute of Technology,Huaian 223001,Jiangsu,China)  
Two methods of the magnetotelluric impedance measurement are provided in this paper.That is,frequency conversion and DFT.The frequency conversion method can completely eliminate the impact of power frequency geoelectricity interference.Specific DFT analysis can accurately measured the excitation signal and geoelectricity interference signal.Thereby,it can provide theoretical basis for the design of high-precision magnetotelluric impedance measurement device.
