12.41 The circuit shown in Fig. P12.41 was introduced in
Problem 5.68. Then, a time-domain solution was sought for
Dout, (1) and Dout₂ (1) for 10, given that v₁(1) = 10u(t) mV,
Vcc 10 V for both op amps, and the two capacitors had no
change prior to t = 0. Analyze the circuit and plot Dout, (t) and
Dout (1) using the Laplace transform technique.
