Abstract
In the case of some fractals, sampling with average values on cells is more natural than sampling on points. In this paper we investigate this method of sampling on SG and SG\(_{3}\). In the former, we show that the cell graph approximations have the spectral decimation property and prove an analog of the Shannon sampling theorem. We also investigate the numerical properties of these sampling functions and make conjectures that allow us to look at sampling on infinite blowups of SG. In the case of SG\(_{3}\), we show that the cell graphs have the spectral decimation property but show that it is not useful for proving an analogous sampling theorem.
