What is feedback amplifier?

The process of injecting a fraction of the output energy of some device back to the input is known as Feedback. It has been found that feedback is very useful in reducing noise and making the amplifier operation stable.

Depending upon whether the feedback signal aids or opposes the input signal, there are two types of feedbacks used - Positive Feedback and Negative Feedback.
The feedback in which the feedback energy i.e., either voltage or current is in phase with the input signal and thus aids it is called Positive feedback.

The feedback in which the feedback energy i.e., either voltage or current is out of phase with the input and thus opposes it, is called negative feedback.

How to Calculate Error Signal?

Error Signal calculator uses Error Signal = Source Signal/(1+(Open Loop Gain of an Operational Amplifier*Feedback Factor)) to calculate the Error Signal, The Error Signal formula is defined as a voltage whose magnitude is proportional to the difference between an actual and the desired position.
