The parameters of the amplifier shown in Figure 8.28 (a) are \(V_{C C}=12 \mathrm{~V}\), \(R_{E}=20 \Omega, R_{1}=14 \mathrm{k} \Omega\), and \(R_{2}=10 \mathrm{k} \Omega\). The transistor parameters are \(\beta=90\) and \(V_{B E}\) (on) \(=0.7 \mathrm{~V}\).

(a) Determine the quiescent value \(I_{C Q}\).

(b) Find the value of \(R_{L}\) such that the maximum power will be delivered to the load.

(c) What is the maximum power that can be delivered to the load if the output voltage is to remain in the range \(1 \leq v_{O} \leq 23 \mathrm{~V}\) ?

(d) Using the results of part (c) and neglecting currents in the bias resistors, what is the onversion efficiency?
