A microphone puts out a peak voltage of \(2 \mathrm{mV}\) and has an output resistance of \(5 \mathrm{k} \Omega\). Design an amplifier system to drive a \(24 \Omega\) speaker, producing \(0.5 \mathrm{~W}\) of signal power. Assume a current gain of \(\beta=50\) for all available transistors. Specify the current and power ratings of the transistors.
