Assume that you need to measure an average temperature in a heated space. You have three identical temperature sensors. Each sensor produces a voltage proportional to temperature such that: 5. Sensor Voltage =.01 * Temperature in degrees Celsius Assume that you have three voltages, Va, Vb, and Ve. You want to take the average of these three voltages in order to compute the average temperature inside the heated space. This circuit has been suggested as a possibility for computing the average. Rf ww Vout Va wew Vb Ve A. Find an analytical expression for Vout in terms of the input voltages and the four resistors. B. Determine if a proper choice of resistors will let you use this as an averager. If you can, then find some appropriate values for the resistors.
