A 1 024-order digital equilibrium filter is designed and realized on EP1C3 series FPGA,which makes full use of the FPGA's on-chip resource by sacrificing time for space,and could also realize the equilibrium characteristics of various frequency responses and functions of the simplified digital equilibrium filter by reloading coefficients,and thus the purpose of designing the filter is attained.

Key words: digital equilibrium filter;FPGA;1 024-order;FIR
