Interpolation of band-limited functions using the approximate prolate series (Corresp.)
J. Knab · IEEE Transactions on Information Theory · 1979
A new series for the interpolation of band-limited functions is found by using an approximation to tho prolate spheroidal wave function as a convergence factor. A truncation error bound is found for the central interpolation of band-limited functions using the new series. It is shown that this bound is lower than other known bounds in many cases of interest.
