| 摘 要： | 采用直接数字合成的方式设计任意波形发生器,逐点读出波形存储器中波形的数据,经过D/A转换和低通滤波器后输出所需要的任意波形,通过改变参考时钟的频率和计数的步长就可以实现波形频率的改变。

| Abstract: | Direct digital synthesis method is adopted to implement arbitrary waveform generator,in which data of the waveform is read out of waveform storage each by each,and the desired waveform is output by D/A convert and low-pass filter.The frequency of output waveform can be changed by altering the frequency of reference clock or the step of counter. |
