摘要
本设计主要基于DDS(直接数字频率合成)芯片AD9851来产生正弦波和方波。其中信号的频率可以通过按键来进行选择,产生的波形可以显示在示波器上。该信号源的工作频率范围是0Hz-70MHz,输出频率的精度可达到0.1Hz。并给出了设计的软硬件的实现方案。
This design is mainly based on DDS （ direct digital frequency synthesis ） chip AD9851 as the core to generate sine wave and square wave. The signal frequency can he selected by the key, the waveform can be displayed on the oscilloscope. The operating frequency range of the signal source is 0Hz-70MHz, the antput frequency precision can reach 0.1Hz. And the realization scheme of software and hardware design is given by the paper.
