Bonus Problem (10 points): In this circuit, the op amp is IDEAL. The op amp is NOT operating in the linear region. In this Circuit, V+=V_. The op amp output saturates at +12v. The output is always at saturation, either positive or negative. The output will “toggle” as Vin crosses a “threshold” voltage. Because of the positive feedback, the threshold voltage changes depending on the state of the output voltage. Find the lower and upper values of the threshold voltages to 5 places of precision.

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)

1.3 A signal source that is most conveniently represented by its Thévenin equivalent has vs = 10 mV and Rs = 1 kΩ. If the source feeds a load resistance RL, find the voltage vo that appears across the load for RL = 100 kΩ, 10 kΩ, 1 kΩ, and 100 Ω.
