Design of IIR Digital Filter Based on FPGA
Hui Zhang, Kun Yang, Si Ming He, Jun Li · Applied Mechanics and Materials · 2013
From the request of practical applications,according to the basic theory of IIR filters, a scheme of hardware implementation is worked out combining with the fact that coefficients of numerator and denominator of transfer function are fixed and the structural feature of selected FPGA. From the clew of implementing stratified ,modularized and parameterized design ,the thesis describes the hardware implementation of the IIR filter with VHDL and schematic diagram design method.
