A potentiometer is used to measure angular position ? of the wheel. A voltage follower is used to isolate the potentiometer from the remaining circuit. The potentiometer being used to measure 360 degrees has a resistance Rp=5.0k?, and is capable of dissipating 0.02W of power in most environments. The diagram of the transducer is shown in Fig. The transducer output contains a noise that is above 1KHz. It is to be connected to a 12-bit analogue to digital converter, having a range between 0 and 5V. Please

  1. Determine the maximum voltage that can be applied to the potentiometer;
  2. Determine the value of series resistor Rs in order to protect the potentiometer if Vs=15V;
  3. If the resolution required is 0.010, determine the value for amplifier gain;
  4. Design a filter with the quality factor Q being 2, and show the circuit diagram.
