Question: 791 Triangular Wave Design There is a need to generate a 12-V 10%, 1-kHz triangular wave. You have a 5-V, 1-kHz square wave.

7–91 Triangular Wave Design There is a need to generate a 12-V ± 10%, 1-kHz triangular wave. You have a ± 5-V, 1-kHz square wave. You recall from your first Circuits course that you can easily design an OP AMP integrator that should be able to produce a triangular wave from a square wave. But the slope of the square wave should not show any visually detectable curve—and it should start at t = 0. The OP AMPs available have a ± 15 V VCC. Design the circuit and verify your design using Multisim. The desired input/output is shown in Figure P7–91.
