A system A has a variable gain G which can be set to any value.Theonly problem with system A is that its gain G is not stable and canfluctuate with+ or minus 10%.for example if u set the gain to 100then it can be as high as 110 or as low as 90. so if the input is 2then the output could be as high as 220 or as low as 180. One wayto minimize the gain fluctuation is to connect a feedback subsystemwith gain H to the system A . Your task is to choose values for Gand H such that the total gain of the system with its feedback is100 with fluctuation that does not exceed + or minus 1%. forexample if the input is 2 then the output should be between 198 and202(99*2 and 101*2)
