| 摘 要： | 介绍了一种基于PC机、单片机、FPGA和数字频率合成技术（DDS）的信号源的设计方法;其中基于FPGA的DDS模块电路采用VerilogHDL语言和原理图相结合的方式设计,上位机的信号源面板以及波形编辑生成系统则基于LabVIEW图形化语言设计;基于FPGA的信号发生器,可以在不改变硬件平台的情况下,随时对信号源系统进行重构或升级,使得应用非常灵活和方便;特别是可以通过USB2.0接口和PC机连接,使得任意波的产生更加方便和快捷;实验结果表明整个设计可以产生0.01Hz-10MHz的任意波及正弦波、方波、三角波等常规的函数信号。

| Abstract: | A method is introduced with structure of PC and single chip microcomputer based on FPGA and DDS in order to achieve the arbitrary wave signal generator.Module of DDS in the circuit design of FPGA combining VerilogHDL with principle chart,as well as data system is based on LabVIEW graphical language.AWG based on FPGA can reconstruct and update on the condition of no hardware platform changed at any time,which makes the application very flexible and convenient.Particularly,it can be connected with PC by USB2.... |
