基于DDS技术的次声波合成方法

Infrasound wave synthesis method base on the DDS technology

介绍了一种采用DDS技术生成高频超声波,进而合成次声波的方法。通过AD9833和微控制器TMS320LF2407生成了两路高频超声波。实验结果表明,该方法是可行的。

An infrasound wave synthesis method is introduced in which DDS technology is used to generate high-frequency ultrasound. DSP TMS320LF2407 and AD9833 are applied as the hardware to generate the two-path high-frequency ultrasound. Experiment results illustrate the method is feasible.
