Hi all,
I have following sinusoidal waveform as my system's input:
And following signal as my system's time-domain response:
Putting both of above diagrams into one (steady-state region) is depicted below:
Now the question is how can I calculate the phase shift caused by system? i.e. phase shift from blue line to red lines.

You should be able to just find the peaks of each and take the shifts between the two or use the hilbert transform to give complex signals, find the 0-phase points of both curves and calculate the shift from those, which will amount to pretty much the same thing.

Thanks for the reply. I think I just did what you mentioned in the first line of your response i.e. finding the peaks of each using cursor and take the shifts between the two
