Digital filtering method in conjunction with finite-difference time domain (FDTD) is proposed for solving the convolution integrals due to ground losses in time-domain transmission line equations. Establishment of the digital filter model and combination of digital filtering with FDTD algorithm is introduced. Example has validated the efficiency of this method.
