摘要:
基于DDS芯片AD9833,提出了一种实现波形可选、频率可调的信号发生器的设计方法,介绍了所设计的信号发生器的硬件电路结构以及软件程序流程图.结合单片机作为控制单元,通过键盘输入信号源的参数,系统可以输出频率在0Hz～12.5MHz内的信号.实验结果表明,该方法具有成本低、精度高、设置灵活、稳定性好等优点.
Abstract:
In this paper，a method of signal generator design based on AD9833，a DDS chip，is proposed，and hardware circuit structure and software program flow chart are introduced． Optional waveform and adjustable frequency can be realized by this method． With the MCU as a central control unit，and setting up the parameters of the source of the signal through the keyboard，the output signal＇s frequency can be changed from 0Hz to 12. 5MHz． The experimental results show that this signal generator has many advantages such as low cost，flexible setting，high precision and good stability．
