Learning outcomes

After the course, the student should be able to

• describe the basics of electrical safety: hazards and safety measures,
• describe the basic concepts of measurement technology and metrology, especially how measurement units are defined and how tractability is achieved,
• describe how electrical nose and disturbances are generated, propagated into the circuits, how this can be modelled and how the effects can be minimized,
• use oscilloscopes and multimeters to measure voltage, current and resistance both in the static and time-varying case,
• describe how several different types of AD-converters work and how this influences their performance
• draw a block diagram for a multimeter and describe how it handles other quantities than DC voltage and how this influences the performance,
• draw a block diagram for the oscilloscope and describe the effects of bandwidth, sampling frequency, input impedance and uncertainty in the instrument,
• use resistive sensors for measurement of temperature and strain,
• describe the basics of modern sensor technology and how sensors based on piezoelectricity, capacitance and inductance are used,
• describe the most basic strategies for computerized measurement systems, like AD-cards and different bus systems,
• describe the basic principles for spectrum analyzers and how the features of the analyzed signal show up in the time domain results ad the frequency desman results,
• be able to compute the standard uncertainty and confidence interval for a combined quantity based on uncertainty information of different kinds for the quantities that contribute to the combined quantity,
• document and in writing report experimental results,
• apply the above knowledge and abilities in problem solving and experimental work, both independently and when working in a group. 

Course main content

• Electrical safety issues.
• Basic concepts of measurements: units and standards, traceability, uncertainty calculations, documentation.
• Measurement of static electrical quantities: introduction to digitalisation, the multimeter.
• Measurement of time-varying quantities: sampling, the oscilloscope.
• Electromagnetic compatibility (EMC).
• Measurement of time-varying quantities: sampling, aliasing, spectrum analysis.
• The computer in the measurement system: hardware configurations, software, virtual instruments.
• Sensors: physical principles, common types, fabrication technologies, applications.
