Phase in time between two signals in time domain

Hi all!

I have two signals in time domain, one is the input and the other is the output.

I compute the transfer function with "tfestimate" command and I use the command "angle" to get the phase in frequency domain.

Since the phase must be computed in a transitory I need the behaviour of that phase in time, because the frequency is not constant so I can't obtain the corresponding phase using the frequency domain.

What do you suggest to obtain the phase time behaviour between those two signals?

Thank you in advance

Hi,

You can use xcorr to compute the cross-correlation between the input and the output. When plotting the correlation over lags you can see the time-shift between both signals.

Perfect, thank you!
