| Abstract: | The configuration and keystone of the FIR filters were analyzed in this article,it advanced a project of DSP based on FPGA.The article designed a FIR filter by windows in Matlab and ascertained coefficients of the FIR.A 16-steps invariable coefficients FIR filter was implemented with the VHDL code,furthermore,the filter was simulated in logic by QuartusII.The results showed that the anticipation of design could be reached. |
