Recent developments in the design and implementation of digital decimators, interpolators, and narrow band filters
Ronald E. Crochiere, L. R. Rabiner · 2005
In this paper we discuss a number of issues concerning the design of optimal decimators, and interpolators and their application to narrow band filtering. We show that a design which is optimized for minimum storage is essentially optimum in terms of its number of required multiplications and additions as well. We then discuss a practical scheme for efficiently implementing decimators and interpolators.
