【Abstract】 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.更多还原
