A BJT emitter follower is coupled to a load with an ideal transformer, as shown in Figure P8.35. The bias circuit is not shown. The transistor current gain is \(\beta=49\), and the transistor is biased such that \(I_{C Q}=100 \mathrm{~mA}\).

(a) Derive the expressions for the voltage transfer functions \(v_{e} / v_{i}\) and \(v_{o} / v_{i}\).

(b) Find \(n_{1}: n_{2}\) for maximum ac power transfer to \(R_{L}\).

(c) Determine the small-signal output resistance looking back into the emitter.
