6. Advanced Topics: Sensor Design and Measurement Uncertainty

Try these first

1. 1.

   What is sensitivity in the context of sensor design?

   Hint

   Think about how sensitive microphones can pick up sounds.

2. 2.

   Define selectivity.

   Hint

   Consider how an FM radio tunes to a frequency, ignoring other noises.

3. 3.

   What is the significance of sensitivity in sensor design?

   • A) Detecting small changes
   • B) Filtering noise
   • C) Cost

   Hint

   Remember why microphones are tuned to capture subtle sounds.

4. 4.

   True or False: Calibration drift refers to the sudden loss of power in a sensor.

   • True
   • False

   Hint

   Think about a device that gets less accurate the longer it operates without recalibration.

5. 5.

   Given a sensor that measures soil moisture, outline an uncertainty budget that includes at least five potential error sources.

   Hint

   Think about factors that may influence the sensor's performance.

6. 6.

   Discuss how the concepts of sensitivity and measurement uncertainty could impact the design of a seismic monitoring system.

   Hint

   Consider real-world implications in earthquake-prone areas.
