Intended learning outcomes *
After the course, the student should be able to
describe the basic concepts of measurement technology and metrology, especially how measurement units are defined and how traceability 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,
describe the design of oscilloskopes and multimeters, and understand their performance influences the result and applicability.
describe how several different types of AD-converters work and how this influences their performance
use oscilloscopes and multimeters to measure voltage, current and resistance both in the static and time-varying case,
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 and 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 orally 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.
