In the optimization formulation, once the known autocorrelations are fixed as constraints, the objective functional completely characterizes the corresponding method of spectral estimation. After observing that this functional involves a sort of spectral flatness maximization, the relationship between the form of its integrand and the salient trends of the various methods is pointed out. This serves as a basis to propose a generalized optimization approach that encompasses some classical estimators and originates new ones.
