  • Abstract
    A technique is described for reconstructing a band-limited function from samples given at arbitrary locations on a finite interval. The method coincides with the Nyquist-Shannon interpolation formula when the samples are regularly spaced. Improvements over alternative techniques are illustrated. It is shown that the method gives the best possible reconstruction in the least-squares sense.
