Design and simulation of FIR digital filter based on DSP Builder

An efficient design method of FIR digital filters based on Altera DSP Builder is proposed by comparing the main method of FIR digital filters.According to the DSP Builder design flow,a eight-order FIR low pass filter model is designed with the aid of Simulink library and DSP Builder toolbox graphics modules,and then the model simulation and verification are completed.The simulation results show that this method is simple,easy to operate,and greatly shortens the development cycle of the filter.The design of FIR low pass filter reaches the technical index of the system,so the method can be better applied to the implementation of the digital signal processing algorithm.
