In a negative feedback amplifier the gain without feedback is 100, feedback ratio is 1/25 and input voltage is 50 mV. Calculate :25(i) gain with feedback (ii) feedback factor.​

Answer» TH feedback and feedback factor are 20 and 5 respectivelyTo find : The gain with feedback and the gain factorGiven : It is GIVEN that the gain WITHOUT feedback is 100, feedback ratio is and input voltage is 50 mV.Let us denote gain without feedback as A and gain with feedback as G. Feedback ratio is denoted by β.Then,Gain with feedback Feedback factor,F is given by ∴Feed back factor Feedback factor Hence, (i)the gain without feedback is 20 and (ii) the feedback factor is 5To learn more..1.
