Implementation of IIR Digital Filter Based on FPGA
Weige Tao · Journal of Electrical & Electronic Education · 2007
The realization method of a infinite impulse response(IIR) digital filter based on FPGA is introduced.This paper proposes four blocks of IIR,which are clock control,time delay,multiply and addition,implemented IIR filter with VHDL and FPGA device.The results show that the method has a better application prospect,good expansibility,strong flexibility and high speed. Thus the method has the better application prospect in engineering.
