Hallo, I have a signal represented by a sum of sinusoids (each having a different frequency and different phase shifts in the time domain). I do an FFT in matlab and get the amplitude spectrum of the wave. But from the phase spectrum i am not able to correlate the phase angles. (angle(signal) gives a different angle from what I expect.. for example if my 3rd harmonic sinus is 50 degress phase shifted, i get something irrelevant like 90 degress) My application would be, I have a random signal and I need to remove only one frequency component from the signal. If I don't have the time-phase shift of that frequency component, then I cant remove it from the signal. How do I get the phase angle from FFT?
