An emitter-follower amplifier is shown in Figure P7.75. Using a computer simulation, determine the upper \(3 \mathrm{~dB}\) frequency and the midband voltage gain for:

(a) \(R_{L}=0.2 \mathrm{k} \Omega\),

(b) \(R_{L}=2 \mathrm{k} \Omega\), and

(c) \(R_{L}=20 \mathrm{k} \Omega\). Use a standard transistor. Explain any differences between the results of the three parts.
