Crepeau and Herzel  (CH) have recently compared the spectral entropy of Powell and Percival  with the standard statistical (Boltzmann-Gibbs-Shannon) entropy in three simple physical systems. Here we compare and contrast these two entropies in a more general way by considering their values for an arbitrary stationary process X(t).
