| Abstract: | The digital filtering formula to calculate apparent resistivity defind by the electric of a horizontal oscillating electric dipole is derived. A filter with only 30 coefficients is determined by use of least square method. A program for pocket-computer to calculate of apparent resistivity is designed, which greatly improves the calculating speed. Compared with the results from analytical formula,the greatest relative error of apparent resistivities is less than two percent. |
