摘要
本文在对DDS原理和AD9854芯片研究的基础上,介绍了一种罗盘测试信号产生模块的设计方案。通过单片机对DDS芯片的控制,可以产生正弦波信号和正弦波调幅信号,满足罗盘定向灵敏度和接收机灵敏度的测试要求。
Based on the researching in the principle of DDS and chip AD9854, This paper presents a design of wireless compass test signal generator. Sine signal and sine amplitude modulation signal can be generated by SCM controlling DDS chip to meet the need of directional sensitivity and receiver sensitivity of compass.
