Consider the feedback system shown in given Figure. The closed-loop gain is Af = -80 and the open-loop gain is A = -2 × 104.

(a) Determine the feedback transfer function β.

(b) The closed-loop gain is not to change by more than 0.01 percent when the open-loop gain changes. What is the maximum allowed change in the open-loop gain?
