For the emitter-stabilized network of Fig. 174 :
a. Determine $A_{v_{\mathrm{N}},} Z_{i}$, and $Z_{o}$.
b. Sketch the two-port model of Fig. 63 with the values determined in part (a).
c. Determine $A_{v_{L}}$ and $A_{v_{v}}$.
d. Change $R_{s}$ to $1 \mathrm{k} \Omega$. What is the effect on $A_{v_{\mathrm{NL}}}, Z_{i}$, and $Z_{o}$ ?
e. Change $R_{s}$ to $1 \mathrm{k} \Omega$ and determine $A_{v_{L}}$ and $A_{v_{s}}$. What is the effect of increasing levels of $R_{s}$ on $A_{v_{L}}$ and $A_{v_{s}}$ ?
f. Determine $A_{i}=I_{o} / I_{i}$
