这里的DDS(直接数字合成)是我在MATLAB中用Simulink基本模块搭建起来的模型,仿真DDS信号的产生,并有一个M文件实现与模型同等的功能,MATLAB爱好者一定不要错过-I build the DDS model using simulink basic model to simulate the DDS source, associated a M file realizing the same function as the model,and,the MATLAB lover

基于dsp builder的DDS实现 在matlab/simulink中，通过dsp builder建模，仿真完成DDS设计-inplement of DDS based on dsp builder.In the matlab/simulink, by dsp builder modeling, simulation design complete DDS

DDS(快速正交调制）生成正弦波形，利用相位累加字进行累加，查找查找表内容输出正弦数据，在通信领域应用很多，我采用的是matlab的simulink进行前期仿真-DDS (fast quadrature modulation) to generate sine wave, the use of the word to accumulate phase accumulation, content output sine lookup table lookup data in many applic
