At time t = 0, the capacitor C in Fig. 2 is completely discharged and Vs = 0 V. At
time t = 20 µs, Vs is stepped up from zero to -1 V and stays at this value until t =
40 µs. Immediately after t = 40 µs, Vs is stepped back to 0 V and remains there.
(a) Derive formulas for the Thévenin equivalent voltage source Vth and the
Thévenin equivalent resistance Rth between the terminals of the capacitor (with
reference direction: node 3 [+] and node 1 [-]).
With R1 = (333) ?, R2 = (8204) k?, C = (5604) pF,
(b) calculate the numerical value of the output voltage Vout at time t = 40 µs, and
(c) calculate the numerical value of the output voltage Vout at time t = 200 µs
