Expert
Feedback is a method whereby some proportion of the output signal of a system is passed (that is, fed back) to the input. This is frequently employed to control the dynamic behavior of the system.
Types of feedback:
a) Negative feedback: This tends to decrease output (however in amplifiers, stabilizes and linearizes the operation). Negative feedback feeds part of a system's output, inverted, to the system's input; usually with the outcome that fluctuations are attenuated.
b) Positive feedback: This tends to raise the output. Positive feedback, sometimes termed to as the cumulative causation, is a feedback loop system in which the system responses to perturbation in the similar direction as the perturbation. In contrary, a system which responds to the perturbation in the opposite direction is termed as a negative feedback system.
c) Bipolar feedback: This can either raise or decrease the output.
