Consider a simple oscillatory system in the xy plane (a point moving in a circle, with constant speed and amplitude). You have the time series of x and y of that point. You can apply the estimator phi = arctg (y/x) (since "amplitude and speed are constants"). Now, supose your system starts at phi=0, so phi (t=0) = 0 rads.
