Abstract :
A new algorithm for smoothing measurement curve is advanced; compare with traditional smoothing algorithm base on rectangular window, the new algorithm can achieve higher degree of smoothness, at the same time distortion caused by smoothness is less, experiment based on measurement curve of filter´s group delay proved this method is of better performance.
