Improved Classes of CIC Filter Functions: Design and Analysis of the Quantized-Coefficient Errors
Biljana Stošić · 2021
The paper proposes the use of identical and nonidentical CIC (Cascaded-Integrator-Comb) sections in generating novel classes of selective, highly effective and low complexity filters, for communication systems. The improved classes are described by analytical method in a compact explicit form. Also, analysis of the effects of coefficient quantization is in focus. The quantized-coefficient errors are considered here based on the number of bits and the implementation algorithms.
