*10. For the network of Fig. 10.53:

(a) Determine AVNL, Zi and Zo.
(b) Sketch the two-port model with the values determined in part (a).
(c) Determine Av and Avs.
(d) Change Rs to 1k and determine Av and Avs. What is the effect of increasing levels of Rs on the voltage gain?
(e) Change Rs to 1k and determine Avnl, Zi, and Zo. What is the effect of increasing levels of Rs on the parameters?
(f) Change RL to 5.6k and determine Av and Avs. What is the effect of increasing levels of RL on the voltage gains? Maintain Rs and its original level of 0.6k.
