Reconsider the circuit in Figure P7.28. The transistor parameters are \(\beta=120, V_{B E}\) (on) \(=0.7 \mathrm{~V}\), and \(V_{A}=\infty\). The circuit parameters are \(V^{+}=\) \(3.3 \mathrm{~V}\) and \(R_{S}=100 \Omega\).

(a) Find \(R_{B}\) and \(R_{E}\) such that \(I_{E Q}=0.25 \mathrm{~mA}\) and \(V_{C E Q}=1.8 \mathrm{~V}\).

(b) Using the results of part (a), find the value of \(C_{C}\) such that \(f_{L}=20 \mathrm{~Hz}\).

(c) Determine the midband voltage gain.
