Some hints and changes for the final:
Problem 1:
For part b) since both the input and load are G then yb does depend on
ya (or vice versa) so you can eliminate yb for part c). Also in part c)
there is a nice cancellation.
For part d) since in V2/V1 there is no dependence upon yb then you can
solve for ya as a function of V2/V1 and since ya is a 1-port, to be
realized by passice components it should be PR.

Change of 12/14/08
Problem 3a) delete the z(s) portion. [but keep it in part b)]
