I have two signals in my circuit and i would like to measure the phase difference between them. Is there a block i could use? If not, how can i measure this difference?

You can use Fourier block to get amplitude and phase angle of each signal, and by subtracting the phase angles you will get the phase difference between your signals.

dear hamed
fourier block uses for Fund, dc. or harmonics, i want to measure the original signal angle, how can i do it ?

Try multiplying the two signals together, and then passing the result through a low pass filter.

You may find the answer from https://en.wikipedia.org/wiki/Phase_detector#Analog_phase_detector

This gives a different answer from the known way .... measuring from the graph directly!!

Phase difference measurment
Its accuracy is based on the sampling time you use.By simply connecting in parallel you can measure phase differnce of any number of signales with resepect to a reference signal.

Hi I came across your model for measuring phase difference in one of my projects. Could you please give me an explanation of how this works ? I did not understand the state-flow chart
