HOW TO ELIMINATE PHASE DIFFERENCE BETWEEN TWO SIGNALS?

Hello all,

I have a problem with removing phase difference between my signals. What i am trying to do is:

Create an angle function Differentiate twice to obtain acceleration Integrate acceleration twice to obtain a position Compare the new position with the initial angle

When compared, there's a phase difference between both signals. I have tried fftshift also, adding a phase shift to the signal to overcome the phase difference but not worked.

I am hoping someone can assist in overcoming the problem. Thank you for your help in advance

Dear james,

If you solved it, let me know how,,, I am facing the same

Use the technique called cross-correlation. Here from @dpb Link

Thanks, I am still trying to understand it as I am new to MATLAB.

Hi Kalyan, thanks for the link. The link to the code example sent is to check the error between two out-of-phase signals however I am looking to correct and remove the phase shift so both signals correlate. Please, can you refer to my code attached? Thanks
