matlab下实现的DDS发生器，可观察其发生信号的波形，频谱。 运行前请先输入 global theta theta=0 -matlab implementation of the DDS generator, may happen to observe the signal waveform, spectrum. Please enter a pre-operational global theta theta = 0

dds信号发生器，基于单片机的信号发生器，可以产生三角波，正弦波，方波。-dds signal generator, microcontroller-based signal generator can generate triangular wave, sine wave, square wave.
