Abstract
Several recent articles [1]-[3] have discussed the use of Lagrange polynomials for band-limited signal estimation. We find error bounds when using Lagrange polynomials for interpolation and extrapolation of finite-power band-limited signals if a finite number of regularly spaced noisy samples are used.Keywords
