What is Stable Sinc Interpolation for Periodic Signals about?

This document discusses numerically stable formulations for sinc interpolation of discrete periodic signals. It begins by introducing sinc interpolation and its application to periodic signals using a Fourier series kernel. It then notes issues with numerical instability in prior formulations at integer values. The main contribution is two new formulations that are numerically stable: 1) Equation 5 expresses sinc interpolation as a finite summation using the discrete Fourier transform (DFT) coefficients of
