Consider the full-wave rectifier circuit in Figure 2.7 of the text. The output resistance is \(R_{L}=125 \Omega\), each diode cut-in voltage is \(V_{\gamma}=0.7 \mathrm{~V}\), and the frequency of the input signal is \(60 \mathrm{~Hz}\). A filter capacitor is connected in parallel with \(R_{L}\). The magnitude of the peak output voltage is to be \(15 \mathrm{~V}\) and the ripple voltage is to be no more than \(0.35 \mathrm{~V}\).

(a) Determine the rms value of \(v_{S}\) and (b) the required value of the capacitor.
