Design of FPGA-Based Cascaded IIR Digital Filter
Janine Xu · Science and Technology of West China · 2011
The hierarchical design was adopted in this paper.Firstly,IIR filter was divided into four function modules,then the VHDL language design was used separately for each module,finally the filter design was completed and simulated.The results of the simulation showed that the IIR digital filter operations faster.
