1) Bibolar junction transistor characteristics are given by the following figure. a) For fixed bias configuration, draw aload line on the chracteristics by \( V_{C C}=21 \) and \( R_{C}=3 \mathrm{k} \Omega \). b) Choose an operating point midway between cutoff and saturation. Determine the value of \( R_{B} \) to establish the resulting operating point. c) Find \( I_{C Q} \) and \( V_{C E_{Q}} \). 2) Consider the following network. Determine \( Z_{i} \) and \( Z_{o} \) and \( A_{v} \).
