Abstract
For the system 
where 
, this note states and proves necessary and sufficient conditions under which a) 
is an estimate of a linear function of 
(i.e., estimates 
), or b) a linear function of is an estimate of (i.e., 
estimates ). The mapping 
has been used previously by the authors to compute the estimator-controller form of a compensator whose state vector had the same dimension as the plant state vector .
