You have a need for an interface circuit that will connect your source to a load with a very high input as shown in Figure P7–56(a). Your interface must have a response that fits within the boundaries shown in Figure P7–56(b). A vendor offers a suitable circuit shown in Figure P7–56(a)

and says that they are willing to change one component without additional cost.

Would you purchase the circuit and, if you will buy it, what change, if any, would you require? Use MATLAB or OrCAD to verify your result.
