4. Assume you have a sensor which outputs a large voltage. You are trying to detect the presence of a signal (not measure the value). This sensor is connected to a Programmable Logic Controller (PLC) which operates at \( 10.0 \mathrm{~V} \pm 0.5 \mathrm{~V} \). Design a circuit which limits the voltage of a sensor to within this range. You have access to exactly one Zener diode of each of the following sizes \( 3.2 \mathrm{~V}, 3.6 \mathrm{~V}, 4.9 \mathrm{~V} \), and 5.2 V , and you have as many signal diodes as you might need. Design this solution two unique ways with no more than 4 diodes in either design. Present your work by drawing the circuit schematics for each of the two solutions.
