Hello everybody,

I have two signals (see figure 3). The first comes from the shaker (blue color/sampling frequency=5000) and the second is a measurement of a plate above the shaker (red color/sampling freq=320). I have tried to correct the delay time, but it is not consistent (apparently there should be a better phase adjustment, see fig. 2). I used xcorr function. I am new to matlab. What could be wrong?

Thanks in advance
