HI,

how can i get time delay from cross correlation ?

why we substract 99 ?

does this value differ if sampling rate changed?

does this code suitable to detect time delay between two signals?

What do you want us to do with a picture?  [Think if I asked you for help and sent you a 4-page listing of Matlab code -- what would you do with it, particularly if there were "crutches" (like an Express VI) that maybe had values hidden inside them?].  You stand a much better chance of getting useful help by attaching your VI.

Hi m.ezzat58

 

      Your code looks familiar and seems to have been taken from

       ... which also answers all your questions.
