The circuit shown in Fig. P12.41 was introduced inProblem 5.68. Then, a time-domain solution was sought foruout1 (t) and uout2 (t) for t ≥ 0, given that ui(t) = 10u(t) mV,VCC = 10 V for both op amps, and the two capacitors had nochange prior to t = 0. Analyze the circuit and plot uout1 (t) anduout2 (t) using the Laplace transform technique.
