| Abstract: | The principle of chirp Z transform (CZT) is presented. To solve the difficult problems of realizing CZT spectrum zooming algorithm in engineering programmes, a design method of a kind of embedded processor (Nios II soft core) is proposed, using Nios IDE platform, simulation experiment is processed on the FPGA development board to achieve the CZT spectrum zooming analysis of a certain power fundamental frequency signal in the specified frequency range. Experiment results show that the method has characteristics of simply designed ,high reliability, achieving of good effect,it has a good practical value. |
