Abstract
The Newton-Gregory interpolation formula is shown to lead to a sampling theorem for signals having Laplace transforms with pole frequencies less than a submultiple of the sampling rate. Plots of spectra computed by Fourier transforming polynomials fitted to short sample sequences are exhibited which accord with this sampling theorem.
