Course content

Measurement uncertainty: Bias/random errors; Selectivity/sensitivity; Calibration.

Noise analysis: Noise, sources and properties, e.g. Thermal noise, 1/f-noise, shot noise, noise in A/D and DA converters; Modeling of noise in electrical circuits.

Sensors and actuators: Static vs dynamic properties of transducers; Transfer functions; Ideal and realistic transducer models; Resolution, linearization, dynamic range, detection threshold.

Sensor types: Environment and bio sensors; Fiberoptical sensors; MEMS; Human's sensing organs, etc

Learning outcome

The course will give students a thorough understanding of the theory of measurement uncertainty and how it affects the performance and accuracy of a measurement system. The subject will also provide knowledge of different types of noise in electronic systems. The course will also provide students with in-depth knowledge of the most important measurement principles in acoustic, optical and radio-based sensors.

Knowledge:
The candidate has
- Basic knowledge of the theory of measurement uncertainty and how it is used in practice.
- In-depth knowledge of how measurement uncertainty and noise contribute to the performance and accuracy of a sensor system.
- In-depth knowledge of the principles of different analog-to-digital converters.
- In-depth knowledge about sources of noise in instrumentation circuits, and the characteristics of the different types of noise that occur.
- In-depth knowledge of the most important measurement principles used in acoustic, optical and radio-based sensors.

Skills:
The candidate can
- perform calculations of noise and measurement uncertainty in an instrumentation system
- Perform practical measurements using sensors, estimate measurement uncertainty, and express it on standard format.
- design an instrumentation circuit and analyze its properties such as noise, dynamic range and linearity.

General competence:
The candidate can
- collaborate on conducting practical measurements with various laboratory sensors.
- write and deliver exercises and lab reports from laboratory exercises.

Learning methods and activities

Lectures; Guest lectures by industry representatives; Compulsary laboratory exercises with associated lectures and compulsary exercises.

Further on evaluation

Folder assessment provides basis for final grade in the subject. In the folder, the written final exam is 75% and laboratory report 25%. The results is entered in %-points, while assessment of the entire folder (final grade) is given by characters. If there is a re-sit examination, the examination form may be changed from written to oral.
If the exam is to be repeated, the whole course needs to be taken.
