摘要
利用FPGA芯片及D/A转换器,采用直接数字频率合成技术,通过EDA开发软件,在线编译DDS信号源设计文件到FPGA开发板上,得出一个频率、相位可调的正弦信号发生器系统模块。经过设计和电路测试,输出波形达到了技术要求。基于FPGA的DDS信号源,只要改变存储波形信息的ROM数据,就可以灵活地实现任意波形发生器。
Use of FPGA chips and D/A converters, using direct digital synthesis techniques, through the EDA software development, online design compiler DDS source documents to the FPGA development board, and arrive at a frequency, phase adjustable sinusoidal signal generator system module . After designing and testing circuit, the output waveform to the technical requirements. FPGA - based DDS signal source, as long as the change in the information storage wave ROM data, the flexibility to achieve arbitrary waveform generators
