DDS实验 程序代码 实验报告 摘要 直接数字频率合成器（Direct Digital Frequency Synthesizer 简称DDS）是一种基于全数字技术，从相位概念出发直接合成所需波形的一种频率合成技术。 本实验利用QuartusII软件设计一个频率及相位均可控制的具有正弦和余弦输出的直接数字频率合成器，具有频率控制、相位控制、测频、显示多种波形（三角波、方波、锯齿波）。实验要求分析整个电路的工作原理，并分别说明了各子模块的设计原理，依据各模块之间的逻辑关系，将各电路整合到一块，形成一个总体电路。之后再完成调试、仿真、编程下载的过程，并对最终结果进行分析，最后总结出在实验过程中出现的问题以及提出解决方案。 关键词： 直接数字频率合成器 累加 控制 波形 Abstract: Direct Digital Frequency Synthesizer is a technology based on fully digital technique,a frequency combination technique syntheses a required waveform from concept of phase. This experiment, using QuartusII software to design a frequency and phase all can control the sine and cosine output has direct digital frequency synthesizer with the functions of controlling frequency and phase,measuring frequency and displaying different waveforms.The paper has analyzed the principle of all work and explained the designing principle of different parts separately.we integrate the modules to form a whole circuit on the basis of the logic relation between the modules. By debugging, simulating, compiling, programming and analysis of the final results, I put forward a matter and give a settling plan.
