11.18 An operational amplifier has a de open-loop gain of100 dB and a uniform —20 dB/decade gain rolloff with a3-dB frequency of 100 Hz. Find the amount of feedbackand the feedback factor required to obtain the following declosed-loop gains. In each case specify the 3-dB frequency ofthe feedback amplifier and the gain-bandwidth product.(a) 60 dB; (b) 40 dB; (c) 20 dB; and (d) 0 dB.

can you make it more obvious. i can't see it properly
