Design the interface circuit in given Figure so that the voltage delivered to the load is v = 10 V ± 10%. Use one or more of only the following standard resistors: 1.3 kΩ, 2kΩ, 3 kΩ, 4.3 kΩ, 6.2 kΩ, and 9.1 kΩ.
These resistors all have a tolerance of ± 5%, which you must account for in your design. Repeat the problem if the desired load voltage is 4.3 V ± 10%.
