Which of the following is a major advantage of negative feedback ?

Which of the following is a major advantage of negative feedback ?

a. Increase in bandwidth and input impedance
b. Decrease in output impedance
c. Increase in output admittance
d. Both (a) & (b)

Correct Answer : d .Both (a) & (b)

Explanation :

Increase in output impedance implies that there is reduction in output admittance. Hence answer is (d).
