Feedback is that property of a closed LOOP control system which allows the output or some other controlled variable of the system, to be compared with the input to the system, so that the appropriate control action may be formed as some function of the output and input.

A feedback is said to exist in a system if the cause and effect between VARIABLES is interrelated.

The characteristics of feedback are: increased bandwidth, increased ACCURACY, REDUCED distortion and non linearity and tendency towards oscillations or instability.
