    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.
