说明：  DDS的基本原理主要由五部分组成，分别是；相位累加器，正弦波形存储器，数模转换器，低通滤波器和时钟，将相位累加器输出的数据作为地址，用来查询表的数据，将取出的正弦数据通过数模转换器输出模拟信号，模拟信号再通过一个低通滤波器输出纯净的正弦波信号。(The basic principle of DDS is mainly composed of five parts: phase accumulator, sinusoidal waveform memory, digital to analog converter, low-pass filter and clock. The output data of phase accumulator is used as address to query the data of table. The extracted sinusoidal data is output analog signal through digital analog converter, and the analog signal is output pure sine through a low-pass filter Wave signal.)
