Effects of sampling on closed form bandlimited signal interval interpolation
Robert J. Marks, Shiao-Min Tseng · Applied Optics · 1985
A bandlimited signal is to be recovered over a finite interval. There are two closed form sampling theorem-type algorithms that can perform this restoration. This paper explores the effects of sampling rate on the restoration uncertainty. Increasing the amount of data near the interpolation interval can either increase or decrease the restoration noise level. In the former case, there is an optimum sampling rate. In the latter, the reduction can be only slight.
