| Abstract: | Based on the techniques of forward and inverse Fourier transformation, the authors discussed the design scheme of ordinary
differentiator used and applied in the simulation of acoustic and elastic wavefields in isotropic media respectively. To compress
Gibbs effects by truncation effectively, Hanning window is introduced in. The model computation shows that, the convolutional
differentiator method has the advantages of rapidity, low requirements of computer’s inner storage and high precision, which
is a potential method of numerical simulation.
