The paper deals with a problem of numerically reliable synthesis of H-inf optimal discrete-time state estimators based on a dual J-lossless factorisations of the delta-domain dual chain-scattering models of continuous-time plants. Necessary and sufficient conditions for the existence of strictly proper H-inf discrete-time estimators are given. Both the regular problem concerning models with no zeros on the stability boundary and the extended problem of models with such zeros are discussed. It is shown that in the latter case some structural constraints always appear.
