ME365 Homework Set 9 Out: October 27, 2011 Due: November 10, 2011 Problem No. 1 Given: A sensor is to be used in the laboratory. The low-pass filter has been added to avoid aliasing. Use the following circuit diagram to answer the questions below. Find: (a) Find the Thevenin equivalent circuit for the sensor. (b) Calculate the sensor’s output impedance (c) Derive the sensor’s frequency response function relating V s to V 1 . (d) Calculate the filter’s input impedance (e) Derive the filter’s frequency response function relating V out to V 1 . (f) Find the total system’s frequency response function (indicate the portion of the response that is due to loading between the sensor and filter). (g) Show how the circuit can be changed by adding an op amp to eliminate the loading. + Vs - Rs Cs Ls Rf Cf + V1 - + Vout - Sensor Filter
