摘要
研究并设计了一种线性调频信号源,采用直接数字频率合成(DDS)技术产生输出信号。介绍了DDS的基本结构和原理,然后对基于DDS的AD9910芯片做了简单的介绍,并在此基础上设计了一个线性调频信号源,并给出了仿真结果。
A linear FM signal source is researched and designed in this paper, which generates signals based on direct digital frequency synthesis(DDS) technology. The principle and basic structure of DDS are presented at first. Then, the DDS-based AD9910 chip is introduced briefly, on the basis of which a linear FM signal source is designed. Finally, the simulation results are given.
