Technique of evaluating rotating stability by autocorrelatio

Update time：2007-09-26 08:26　　　 Viewed：次

Autocorrelation function can express the strength of periodic signal (maximum 1). If from a blade or coupler, the higher the autocorrelation function of the electromagnetic signal swing range will be smaller, stability will be the stronger. On the contrary, the smaller the numerical said swing is very severe. 
As one of the assessment methods, the extent of the blades for every revolution of the signal is very important, can make use of a rotating time calculated on the basis of relative value.
