IIR Digital Filter Design and Implementation Based on FPGA
Tao Feng, Yanliang Yang · International Conference on Electronics, Communications and Control · 2012
This paper is based on the Argument Principle stability constraints, given the use of Mat lab to design IIR band-pass digital filter. Through the Simulink simulation environment, the designed finite word length of IIR digital filter is dynamic simulated. Then, realize the digital filtering in the FPGA development board. From the results of simulation and hardware testing, the frequency selection characteristics of the designed IIR digital filter is good, not only satisfy the filter performance, but also optimize hardware resources.
