What do you mean by the term feedback? And describe various types of feedback.

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.
A bipolar diode based logic circuit is demonstrated in given figure. Establish the output voltage as the supply voltage, VCC, as well as the circuit parameters for all combinations of input logic levels along with VH = VCC and VL = 0V. Draw waveforms demonstrating the input
