The calculation averages complex points sampled uniformly in *time*, not uniformly along the *arc length* of the trajectory. Because the signal g(t)g(t) modulates the radius and the rotation speed varies with frequency, equal time intervals do not correspond to equal distances traveled along the curve.

Conditions: Sampling is done at uniform time intervals tkt_k.; The path is defined by zf(t)=g(t)e−2πiftz_f(t) = g(t)e^{-2\pi i ft}.
