DDS(直接数字频率合成器)的整个工程文件,已在板子上运行通过,实现了正弦波、方波、三角波的调幅、调频，尚未实现调相，希望有志同道合者可一同完善！-DDS (direct digital frequency synthesis), the whole project documents, the board has been run through, achieved a sine, square, triangle wave amplitude, frequency, phase modula

本程序是用Qt做的显示三种基本波形的Demo。 三角波，方波，正弦波。可以启动和停止，能改变幅值和偏移量。-This procedure is to do with Qt, the Demo show the three basic waveform. Triangle wave, square wave, sine wave. You can start and stop, change the amplitude and offset.

波形发生器可输出正弦波，锯齿波，方波，三角波等-Waveform generator can output sine, sawtooth, square, triangle wave, etc.
