In control theory, a state observer or state estimator is a system that provides an estimate of the internal state of a given real system , from measurements of the input and output of the real system. It is typically computer-implemented, and provides the basis of many practical applications.

An observer is one who engages in observation or in watching an experiment .
Read moreHow do you explain the observer effect?
The observer effect is the fact that observing a situation or phenomenon necessarily changes it . Observer effects are especially prominent in physics where observation and uncertainty are fundamental aspects of modern quantum mechanics.
Read moreWhat is the Observer design pattern explain briefly its importance with an example?
Example. The Observer defines a one-to-many relationship so that when one object changes state, the others are notified and updated automatically . Some auctions demonstrate this pattern. Each bidder possesses a numbered paddle that is used to indicate a bid.
Read moreWhat is Observer pattern in C++?
Observer in C++ Observer is a behavioral design pattern that allows some objects to notify other objects about changes in their state . The Observer pattern provides a way to subscribe and unsubscribe to and from these events for any object that implements a subscriber interface.
Read moreWhat are observers in code?
The observer pattern is a software design pattern in which an object, named the subject, maintains a list of its dependents , called observers, and notifies them automatically of any state changes, usually by calling one of their methods.
Read moreAre listeners observers?
The object which is being watched is called the subject. The objects which are watching the state changes are called observers or listeners .
