dear answers expert answer asap and well
Q3 (a) An amplifier system without feedback has the following specifications: Open loop gain: 90 Input impedance: 25kQ Output impedance: 5kQ (i) (ii) If the amplifier system employs negative feedback and the close loop gain is 9.5, calculate the system feedback factor, p. Suppose the negative feedback topology used for the amplifier system in Q3(a)(i) is a current shunt feedback, determine the amplifier, input impedance and output impedance of the amplifier with feedback.
