Abstract
In this paper we simulate Digital Down Converter (DDC), as a chain of CIC and FIR filters, in order to optimize filter´s coefficients. The goal is to achieve the widest possible bandwidth with four DDCs that will restrain fake peaks. DDC model is based on the DDC in Graychip´s GC4016 Multi-Standard Quad DDC Chip. We use program MATLAB© to design and analyse four fixed-point DDC filter chains for a WB (Wide Band) application.
