83390078DDS
- DDS的工作原理是以数控振荡器的方式产生频率、相位可控制的正弦波。电路一般包括基准时钟、频率累加器、相位累加器、幅度/相位转换电路、D/A转换器和低通滤波器（LPF）。频率累加器对输入信号进行累加运算，产生频率控制数据X（frequency data或相位步进量）。相位累加器由N位全加器和N位累加寄存器级联而成，对代表频率的2进制码进行累加运算，是典型的反馈电路，产生累加结果Y。幅度/相位转换电路实质上是一个波形寄存器，以供查表使用。读出的数据送入D/A转换器和低通滤波器。-DDS works
cordic_atan
- 用verilog语言实现计算反正切函数，在软件无线电中解调PM/FM中使用的尤为频繁。上传的压缩包是modelsim工程，基于6.5c,里边包含一个完整的PM波产生以及解调过程的matlab文件仿真，并取其中间的I和Q支路做为verilog文件的输入，并将其借条输出与MATLAB实际解调输出作比较。 鉴相器的设计基于CORDIC算法，其精度取决于迭代的深度。由于工程实际运用只需要解调出atan值，并不需要绝对的值，所以并没有给予加权，需要的同学可以自己加上。-Calculated usin
