| 摘 要： | 在此基于DDS技术进行任意波形发生器的研制。以单片机为控制核心，采用FPGA芯片EP1C3T144C8，通过使用相位累加器和波形ROM等模块实现DDS功能，可产生正弦，方波，三角波与锯齿波等常规波形，而且能够产生任意波形，并通过键盘一一对应波形，从而满足研究的需要。最后给出系统产生的测试数据，并对影响频谱纯度的杂数与噪声产生的原因进行分析。

| Abstract: | The development of arbitrary waveform generator based on direct digital synthesis(DDS) technology is discussed in this paper.EP1C3T144C8(FPGA chip) is adopted and SCM is taken as a cybernetics core in the design to realize DDS function through phase accumulator and waveform ROM.The generator can produce not only the conventional waveform such as sine wave,square wave,triangle wave and sawtooth wave,but also the arbitrary waveform.It can match the needed wave by keyboard and meet the requirement of the relat... |
