摘要
介绍了多采样率转换在光纤陀螺中的应用 ,通过分析并设计了多级抽取滤波器 ,并将此算法在DSP中实现。采用此种滤波方案 ,可以更有效地保证有用信号不产生混叠失真 ,从而提高了光纤陀螺的测试精度。
The implemention for multi-rate digital signal processing in FOG is discussed,and a method of multistage decimation filters is designed.We realized the method with digital signal processor.Based on the results,we can find that,by using the method,the FOG processes lower zero drift and higher sensitivity.
