Question

An amplifier has open loop gain of 100, input impedance 1 k&Omega; and output impedance 100 &Omega;. If negative feedback with &beta; = 0.99 is used, the new input and output impedances are-A-10 &Omega; and 1 &Omega;B-10 &Omega; and 10 k&Omega;C-100 k&Omega; and 1 &Omega;D-100 k&Omega; and 10 &Omega;-C-100 k&Omega; and 1 &Omega;

APTITUDE CRACK · Accepted Answer

C 100 k&Omega; and 1 &Omega;  Input impedance with feedback = (1 kΩ) (1 + 100 + 0.99) = 100 kΩ. Output impedance with feedback = .
