What are the advantages of negative feedback

WIN FREE BITCOIN

(i) Highly stabilized gain.

(ii) Reduction in non-linear distortion.

(iii) Increased bandwidth,i.e.,improved frequency response.

(iv) Increased stability of circuit.

(v) Less amplitude distortion.

(vi) Less frequency distortion and less phase distortion.

(vii) Increases input impedance and decreases output impedance. In other words,the input and output impedance and decreases can be modified as required.

(viii) Reduces noise and less harmonic distortion.

(ix) The transfer gain Af of the amplifier with feedback can be stabilized against variations of the h-parameters of the transistor.

(x) The significant improvement in the frequency response and in the linearity of operation of the feedback amplifier compared with that of the amplifier without feedback.
