1.1 For the signal-source representations shown in Figs. 1.1(a) and 1.1(b), what are the open-circuit output voltages that would be observed? If, for each, the output terminals are short-circuited (i.e., wired together), what current would flow? For the representations to be equivalent, what must the relationship be between vs, is, and Rs? For (a), voc = vs(t); for (b), voc = Rsis(t); for (a), isc = vs(t)/Rs; for (b), isc = is(t); for equivalency, vs(t) = Rsis(t)
