Hi all,
I want to do an ordertrack of a vibration signal. The Matlab function 'ordertrack' only calculates the amplitude, but no phase can be extraced. What I do now, is doing an FFT for each revoluation en get the phase data from the fft. Does anybody know if there is a better solution?
Kind regards,
Nick

To get the instantaneous phase of a signal x,
xh = hilbert(x);
xphase = angle(xh);
