Hi,
I would like to trace the evolution of the phase between two signals ( voltage and current ).
How can I do this with flexpro 8 ?Thx for help.

E.g. you could calculate the level crossings (level 0) using the event isolation analysis object to receive the time delay. After that you can use the following formula:
phase = 2 * PI * frequency * delta t06.11.2009 à 00:00 #33795mathias andriamisainaParticipantIt does not really answer my needs because the phase is not constant between the two signals and I would like to trace the phase shift evolution.
I already have a method using power calculation but it works only with pure sine signals.07.11.2009 à 01:27 #33796Bernhard KantzParticipantYou can calcalute the phase of as signal using the FourierSpectrum analysis object (result type phase).
Calculate the phase of both signals. After that you can calcuate the difference between both phase signals: Phase1 – Phase2 -
