The formulation deals with discrete observables. Both the relations with state-dependent and state-independent bounds are presented. The entropic bounds are illustrated within the distinction between non-orthogonal states.4 pages, no figures. Improved state-dependent entropic bounds are presented. The bibliography is extended.
