Intended 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.

Based on recommendation from KTH’s coordinator for disabilities, the examiner will decide how to adapt an examination for students with documented disability.
The examiner may apply another examination format when re-examining individual students.
Several smaller tests during the course. The theoretical teaching in each subsection will be concluded with a web-based test or a short written test.
The written exam at the end of the course is strongly related to the labs and includes lab reporting based on notes from the Lab exercises
