Abstract

The digital filter is widely used in many situations with the development of digital signal process techniques. The basic theory of digital filter is briefly described at first. Then the common design methods of FIR are introduced, and different window functions are demonstrated in detail. And different design method of IIR methods are compared and analyzed. For a given experimental example, the required FIR and IIR low-pass digital filters are designed respectively by MATLAB program function and FDAtool. Finally, the simulation models are constructed in Simulink, and the results show that both designed FIR low-pass digital filter and IIR low-pass digital filter can filter the mixed signals to obtain the required 1 MHz sine wave.
