Some errors of gravity and magnetic anomalies calculated in terms of Fou-rier transformation are caused by discretizating and truncating of their spectra.The authors have evaluated the folding and wrinkle of the calculated anoma-lies and sugest that a convolution and folding be needed before anti-Fouriertransformation to get rid of such errors. The paper also deals with the singula-rity problem of the spectrum function.
