The ideal feedback transfer function is given by Equation (12.5).

(a) Assume the feedback transfer function is \(\beta=0.15\). Determine the loop gain \(T\) and the closed-loop gain \(A_{f}\) for (i) \(A=\infty\), (ii) \(A=80 \mathrm{~dB}\), and (c) \(A=10^{2}\).

(b) Repeat part (a) for \(\beta=0.25\).

Equation 12.5:-

Ap Af(s) Af (s) = (1+BA) 1+ 1 S WH (1+BA)
