Course syllabus - Measurement Technique

Objectives

The purpose of the course is to provide knowledge on how to apply the most appropriate measurement method and instrumentation for a particular application, and how to transfer measured quantities into digital data in a computer. The course also provides knowledge about the physics behind measurements of some quantities.

Learning outcomes

After completing the course, the student should be able to: 
1. orally and in writing show understanding of how measurements of a number of physical parameters are performed and how to analyse the limitations of measurements 
2. in practice show an understanding of the different errors introduced during measurements and calibrations  
3. understand how to store measurement data, and to practically apply basic statistics for analysis of series of measurement data 
4. understand and carry out data acquisition, all the way from the sensor signal to the processing unit 
5. apply and explain basic signal processing methods and filters in order to analyse the frequency content of a signal

Course content

Handling of the most common measurement instruments. The International System of Units and standard units for measurements. Measurements of voltage, current, resistance, temperature and magnetic field. Measurement errors, resolution, accuracy, precision, repeatability and reproducibility, normal distribution, standard deviation, mean value, relational databases. Definitions of different signal types, sampling theorem applications in measurement technique, basic AD/DA conversion, frequency analysis and its application in filtering, and filtering.

Specific requirements

Electronic Systems 7,5 credits and Single Variable Calculus 4 credits.

Examination

Laboratory work (LAB1), 1,5 credits, marks Fail (U) or Pass (G) (examines the learning outcomes 1-3 and 5)
Project (PRO1), 3 credits, marks Fail (U) or Pass (G) (examines the learning outcomes 1, 2, 4 and 5)
Written examination (TEN1), 3 credits, marks Fail (U), 3, 4 or 5 (examines the learning outcomes 1, 3, 4 and 5)

A student who has a certificate from MDU regarding a disability has the opportunity to submit a request for supportive measures during written examinations or other forms of examination, in accordance with the Rules and Regulations for Examinations at First-cycle and Second-cycle Level at Mälardalen University (2020/1655). It is the examiner who takes decisions on any supportive measures, based on what kind of certificate is issued, and in that case which measures are to be applied.

Suspicions of attempting to deceive in examinations (cheating) are reported to the Vice-Chancellor, in accordance with the Higher Education Ordinance, and are examined by the University’s Disciplinary Board. If the Disciplinary Board considers the student to be guilty of a disciplinary offence, the Board will take a decision on disciplinary action, which will be a warning or suspension.
