Hve a few question s studying for an exam on monday. any help would be much appreciated. A voltage amplifier has an open- loopgain of 100db and a bandwidth 10hz. it is required to increase the bandwidth to 60 khz by application of negative feedback. (i ) the gain bandwidth of the amplifier (ii) the closed gain in db (iii) the percentage feedback Sketch the open - loop and closed-loop frequency response. indicate clearly the open - loop and closed loop bandwidth.
