内容摘要:
In this presentation, the ill-posed problem of computation of the Fourier transform ^ f for a noisy band limited signal fis discussed. Here, ^ f is computed by a regularized Fourier serieswhich is obtained bya regularization of the Fourier transformed sampling formula of Shannon. If the regularization parametertends to zero, the uniform and L2-convergence of this method is proved. Numerical examples show the performance of this approach. And the results are extended tothe two-dimensional case.
