本程序主要用于DDS算法的验证,可以生成正弦波，占空比可调的方波，三角波；其中频率控制字可调，生成波形的频率也可调。-This procedure is mainly used for verification DDS algorithm, can generate sine wave with adjustable duty cycle square wave, triangle wave including adjustable frequency control word to gene

基于fpga的DDS实现,可以实现1hz-40Mhz的正弦信号，方波信号，锯齿波信号，三角波信号等的输出-DDS fpga-based implementation can be achieved 1hz-40Mhz sine signal, square wave signal, sawtooth signal, the output of the triangular wave signal, etc.
