A Generalized Signal Reconstruction Method for Designing Interpolation Filters
Ioannis L. Syllaios, Poras T. Balsara, Oren Eytan Eliezer · 2006
A generalized signal reconstruction method is presented for the development of digital FIR interpolation filters, applicable to an analog reconstruction filter impulse response with finite duration that extends to an integer number of the input sampling periods. The technique produces efficient interpolation filter structures for both polynomial and non-polynomial based impulse responses, and could minimize implementation requirements (area, power) for filter designs involving sampling rate conversion.
