Feedback Amplifier

Question
7 out of 9
 

What is the effect of negative feedback on the input impedance and output impedance of a voltage-series feedback amplifier?

 

Due to negative feedback, the input impedance of a voltage-series feedback amplifier increases by a factor (1 + βA) whereas the output impedance of voltage-series feedback amplifier decreases by a factor (1 + βA).
