The voltage source in the circuit in Fig. P 7.96(a) is generating the triangular waveform shown in Fig. P 7.96(b). Assume the energy stored in the capacitor is zero at t = 0 and the op amp is ideal.
 a) Derive the numerical expressions for vo(t) for the following time intervals: 0 ≤ t ≤ 1 µs; 1 µs ≤ t ≤ 3 µs; and 3 µs ≤ t ≤ 4 µs.
 b) Sketch the output waveform between 0 and 4 µs.
 c) If the triangular input voltage continues to repeat itself for t 7 > 4 µs, what would you expect the output voltage to be? Explain.
