Paper, in-depth analysis of the filter system design features, principles and techniques to achieve the key, described the use of MATLAB for bandpass filter design and simulation of specific methods. Finally the whole design is described using VHDL, the simulation in Quartus Ⅱ. As a result FPGA, allows the filter to achieve simple structure, saving hardware resources, speed up the development schedule, Quartus Ⅱ compared with the Matlab simulation result shows the correctness of the design. Therefore, this design of FIR digital filter has better real-time, flexibility and practicality. 目录
