| Abstract: | This article studies multiplying operation of FIR in FPGA and explains the principles from multiplication to FFT algorithm and DA algorithm. In addition, the FIR filter designed by adopting the two algorithms has passed the test EPF10K30 device in Altera company, and also proved that the two algorithms are feasible and highly efficient and that the performance of the realized filter is superior to the FIR filter realized by using DSP and the traditional methods. |
