Phase computations through phase equations methodology. The events in the SSA-generated sample path are recorded. From the RRE, the limit cycle and isochron approximation information is computed. Phase equations make use of these two pieces of information to compute the instantaneous phase corresponding to each point in the sample path. The first-order phase equation as adapted to this methodology is given in the figure.
