摘　　要：设计了一种双路低频信号发生和分析系统,系统是基于FPGA设计的。FPGA是整个系统的数据处理核心。此系统能够同时产生两路低频信号,同时还能够把两路信号叠加进行频谱分析,并且还能够实现幅度和频率的提取,提取到的信息能够通过液晶模块进行显示。测试结果表明,此系统操作简单,易于实现,并且稳定可靠。具有广阔的应用空间。Articles designed a dual frequency signal generation and analysis system,which is based on the FPGA design. FPGA is the core of the entire system of data processing. This system can simultaneously produce two low frequency signals,and signals can also be superimposed on the two spectral analysis. It achieves the amplitude and frequency of the extraction. The extracted information can be displayed by the liquid crystal module. Test results show that this system is simple,easy to implement,stable and reliable. It has broad application space.
