在MATLAB中使用DSP Builder模块，利用DDS原理产生任意频率的正弦波-sinwave

通过调用DSP builder中的设计模块设计的DDS，已经验证通过，可调节频率字来调节输出频率-Through the design module called DSP in the builder DDS, which has been verified by word frequency, can be adjusted to adjust the output frequency

采用DSP Builder设计的DDS信号发生器-The DDS signal generator using DSP BUILDER design
