A new method in harmonics testing

This paper presents a method to design a harmonics tester. The method makes use of modern DSP technology which uses the tool of DSPbuilder of Altera. The design process is to fulfill the FFT computing in MATLAB. Then through being translated and edited, the file is downloaded to FPGA. Finally, the SOPC system is setup by the FPGA, peripheral sampling, keyboard and display circuits. The method can greatly improve the developing efficiency, shorten developing period and reduce costs. The practice has proved the accuracy and validity of the method.
