Phase Shift between 0 and pi

please how can I calculate the phase shift of two signals using a range of 0 to π

[Spencer Chen]

Have you tried FFT?

[TTA]

Yes ....I am using FFT. But I am not dealing with some or cosine signal. I am dealing with a fluctuations from a temperature measurements.

I wonder if you have a good understanding on FFT :-)

Remember that the signals are discrete and thus the m shift in the time domain results in the multiplication of the following term in the frequency domain:

so the phase shift is obviously given by:
