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

DDS信号生成模块，使用MATLAB产生查找表，可输出方波、三角波、锯齿波、正弦波-DDS signal generator module, using MATLAB to generate a lookup table can output square wave, triangle wave, sawtooth, sine

在dac 上显示一个波图，刚刚输出的时候是sine 的图 开动按钮后发出不同的图像-Write a C program that creates a waveform generator. It should start by outputting a sine wave to DAC0. Each time SW1 is pressed then released, the wave form should change, first to a triangle wave, then
