Abstract
This paper designs a new FPGA-based spectrum analyzer. The analyzer uses FFT technology and takes full advantage of Nios II soft-core processor to complete signal acquisition, filtering, signal processing, digital FFT, and eventually displays the data on the LCD with the help of LCD, AD chips, filters and some peripheral circuits. The System testing result shows that the digital spectrum analyzer can meet the demands of the real-time spectral analysis with the frequency scope of 0- 1 MHz well. The whole system works steadily and operates expediently and the cost is also much lower than the others.关键词
