Negative feedback: When the feedback energy is out of phase with the input signal, it is called negative feedback.
Negative feedback reduces the gain of the amplifier. That is why, it is sometimes called degenerative or inverse feedback. However, the advantages of negative feedback are-
1.Higher input impedance
2. Lower output impedance
3. Better stabilized gain
4. Reduction of noise
5. Improved frequency response
