information and retain the one corresponding to the most recent measurement for either calculating
the best possible estimate in terms of minimum mean square error or minimizing a quadratic cost.
The mechanisms described so far rely on the existence of both a single sensor–actuator pair, as
well as a designated estimator/controller, which is
