How to measure the phase difference between two signals in simulink?

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?

[Azzi Abdelmalek]

i don't think such block exist,

[Zhongyou Wu]

try the "complex phase difference" model

[Hamed Bahmani]

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 ?

Answer 1

[Rick Rosson]

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

[Ross]

Can you explain how this works please?

[shatha hanya]

how does this methode give the phase difference ?

[Sukvasant Tantikovt]

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

Answer 2

[Hamed Bahmani]

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.

what block should i use with fourier to display the mag and phase ? scope ? or display

Helped a lot!!

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.

Works Great. Thank You Very Much.

Hello, i use your file in my proyect, i want to know if i can share it and give you the credits. i can give you my email for more details if you want. thanks

@Mateo Morales Farias you can

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
