Unformatted text preview: regions of Vin from 0 to Vref. b. What is the function of the circuit? c. What is the resolution of the circuit? d. What is the worst case accuracy of the ranges of Vin (from part a.) when the resistors are rated to 10%. 2. Using the following circuit of a LVDT, where the shaded area represents a ferromagnetic rod that can be displaced in the +x or –x directions. Assume all three coils are of equal inductance. d d R1 +x + d R1 - Vin - Vo + R2 -x R2 d d a. Find an expression for Vo as a function of Vin for −d ≤ x ≤ d . Hint: Assume ideal LVDT and op-amp and use KCL. Also assume that the values for resistances R1 and R2 are very large. V b. Sketch the ratio o as a function of x...
