Design the interface circuit in Figure P3-67. so that the voltage delivered to the load is \(v=10 \mathrm{~V} \pm 10 \%\). Use one or more of only the following standard resistors: \(1.3 \mathrm{k} \Omega, 2 \mathrm{k} \Omega, 3\) \(\mathrm{k} \Omega, 4.3 \mathrm{k} \Omega, 6.2 \mathrm{k} \Omega\), and \(9.1 \mathrm{k} \Omega\). These resistors all have a tolerance of \(\pm 5 \%\), which you must account for in your design. Repeat the problem if the desired load voltage is \(43 \mathrm{~V} \pm 10 \%\).
