Description : Define negative and positive feedback

Last Answer : 1. Negative feedback: Feedback in which feedback signal is out of phase with input signal and it decreases output is called negative feedback.  2. Positive feedback: Feedback in which feedback signal is in phase with input signal and it increases output is called positive feedback.
