| Abstract: | This paper has introduced the work principle of the automatic collecting systems for seismic-electrical signals,which is in the north-south direction at earthquake graduate school of Beijing University of Technology.And the study objects are two round chart signals and two seismic-electrical signals received by automatic collecting systems.Analyzed the signals using the theory of Fourier Transform and Wavelet Transform and Contrasted the frequency domain character between the two kinds of signals.In this paper,a trendline of seismic-electrical signal has been given.Offered some useful data for the study of this field. |
