In this video, you will find a clear concept of a feedback amplifier. Gain of feedback is derived and explained.

Amplifier: An electronics device that increases (amplifies) the input signal (voltage, current).
Feedback: Transfer of energy from the output of a system to its input.

Feedback can be of two types:

1) Negative feedback: The feedback signal diminishes the magnitude of the input signal.

2) Positive feedback: The feedback signal enhances the magnitude of the input signal.
