Based on the theoretical analysis of two types of mathematical filters, the paper realizes the simulation of IIR and FIR digital filters based on MATLAB. Finally, the simulation results of the two types of filters are compared and the design features of different types of filters are summarized . The research in this paper is instructive for the design of the filter.
