Question
**Problem 5:** Use superposition to design a circuit that allows fine and coarse voltages to be combined. Select resistor values \( R_1 \), \( R_2 \), and \( R \) that allow \[ V_{\text{tune}} = \frac{1}{20} V_{\text{fine}} + \frac{1}{2} V_{\text{coarse}} \] **Circuit Diagram Description:** The circuit diagram consists of two voltage sources, labeled \( V_{\text{coarse}} \) and \( V_{\text{fine}} \), and three resistors, labeled \( R_1 \), \( R_2 \), and \( R \). - \( V_{\text{coarse}} \) is connected in series with resistor \( R_1 \). - \( V_{\text{fine}} \) is connected in series with resistor \( R_2 \). - The two branches meet at a junction that connects to resistor \( R \). - Resistor \( R \) is connected to the output voltage \( V_{\text{tune}} \). The objective is to configure the resistors such that the output voltage is a specific combination of the input voltages from the coarse and fine adjustment sources.
