摘要
采用了直接数字频率合成技术(DDS)和计算机控制技术,选择美国Analog Devices公司的高度集成DDS芯片AD9851和AT89S52单片机作为控制器件,设计了一种基于DDS的程控信号发生器。用C语言进行了软件应用设计。实验结果表明,该信号发生器能较好地产生较高稳定度的激励信号,具有较高的实用价值。
A program-controlled signal generator based on DDS was designed,which used direct digital frequency synthesis technology(DDS) and computer control technology,selected AD9851 and AT89S52 SCM of Analog Devices Company as control devices and realized software application design with C language.The signal generator can produce stable excitation signal and has high practical value.
