Abstract :
Expressions are presented which quantify the effects of mis-estimation of the support of the object function on the regularised minimum-norm solution to the discrete bandlimited extrapolation problem. Computational results based upon these expressions are used to demonstrate the variation in the sensitivity of the regularised minimum-norm solution as a function of the regularisation parameter and space-bandwidth product.
