| Abstract: | IIR (Infinite Impulse Response) digital filters are widely used in many fields. In this paper, it introduce how to design a bandstop IIR digital filter in Matlab. And then divided it into second order filters called biquads. The implementation is simulated using the Verilog HDL in Quartus II. |
