摘要
信号源是一类十分重要的仪器,在测控、通信、导航、雷达、医疗等领域有着广泛的应用。该文首先对直接数字合成(DDS)原理进行分析,提出了一种基于DDS技术的信号源实现方案,可输出正弦波、三角波和方波。最后,对所设计的信号源进行测试,并对测试结果进行分析。
Signal source is very important in modern electronic instruments. It is widely applied in many fields such as communication, navigation, radar, measure and control. This paper firstly analyzes the basic principle of Direct Digital Synthesis(DDS), and then puts forward a scheme of realizing Signal source by using DDS technology. The Signal source can output sine wave, square wave, triangle wave. Finally, verify the parameters of the Signal source and analysis test results.
