Dynamically tuned digital filters based on FPGA
Sergiyenko A.M., Lesyk T.M. Dynamically tuned digital filters based on FPGA //Proceedings of International Scientific Conf. «Modeling-2010». – Kiev: IPME. –2010. –V.3. –p.161-166. (in Russian)
Features of the dynamically tuned IIR filters configured in FPGA are considered. The filters utilize masking properties of the all-pass digital filters, which have the delay factors z-k. The mapping of the filter algorithm is implemented using pipelining and C-slow retiming techniques, which provide the minimized hardware volume and high clock frequency of the resulting filters.
