Abstract
Inequalities are developed for the fraction of a bandlimited function' s L(p) norm that can be concentrated on any set of small "Nyquist dens ity." Two applications are mentioned. First, that a bandlimited functi on corrupted by impulsive noise can be reconstructed perfectly, provid ed the noise is concentrated on a set of Nyquist density < 1/pi; secon d, that a wideband signal supported on a set of Nyquist density < 1/pi can be reconstructed stably from noisy data, even when the low-freque ncy information is completely missing.
