Hi,

I have two sensor recorded signal, I have filtered then with band pass filter. I have seen poor correlation coeffcient among these two signal which was the main task. My teacher said the poor correlation is due to phase shift, I detected phase shift but dont know how to correct or remove them, to obtain better correlation. both the signals are almost sinosoidal.

Can some one help please.

Let's say you have a phase shift that works out to 100 samples based on your sample rate. If you're just doing analysis on a recorded signal can't you just shift the filtered signal back by 100 elements?
