In this appendix we will offer proof of the convergence of the sequence of order- scaled kernels to the infinite-order scaled kernel, in the limit. The point is to show that the infinite sequence of real functions , with , converges in the limit to a definite regular real function with finite support within , which we denote as . In addition to this, we will establish that the infinite-order scaled kernel is a function, and that it is not an analytic function in the real sense of the term.
In order to do this we must first establish a few more properties of the first-order filter, in addition to those demonstrated in [3]. We will also have to examine more closely some aspects of the process of construction of the infinite-order scaled kernel.
