摘要
介绍了一种应用DDS芯片AD9850辅以单片机芯片89C51构成函数发生器的方法,文中详细分析了波形的产生原理,讨论了波形产生方法和频率调整方法。实测结果表明,本文所讨论的方法和研制的系统是可行的、有效的。
This paper proposes a method for developing function generator,in which AD9850 and 89C51 are employed.We illustrate not only the theory and means of synthesizing wave but also the adjustment of frequency.The results of experiments verify that the technique and the system in this paper are feasible and effective.
