3. The 555 timer has an OFF time of 0.7 RgC and an ON time of 0.7(Ra+Rg)C. A capacitive displacement sensor is connected in parallel with the 1000 pF capacitor. The capacitive displacement sensor has a sensitivity of 3475pF/m and is used to measurement work-piece displacement from 1 cm to 2 cm. (a) What range of frequency corresponds to the 1- to 2-cm displacement of the sensor? (b) Plot the frequency change versus displacement and determine whether the curve is linear or not? Vcc
