Course information

Content and learning outcomes

Course contents *

  • Basic concepts of measurements: units and standards, traceability, uncertainty calculations, documentation.
  • Measurement of static and dynamic electrical quantities: sampling, discretization, aliasing, spectrum analysis.  Applications with multimeter and oscilloscopes.
  • Electromagnetic Compatibility (EMC).
  • The computer in the measurement system: hardware configurations, software, virtual instruments.
  • Sensors: physical principles, common types, fabrication technologies, applications.

Intended learning outcomes *

On completion of 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 noise and interference arise, how they, in simple cases, can be modelled and how they can be minimized,
  • describe the design of oscilloscopes and multimeters, and understand how their performance influences the measurement result and applicability,
  • describe how several types of AD-converters work and how this influences their sensitivity to noise in the input signal,
  • 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 modern sensor technology and how sensors based on piezoelectricity, capacitance and inductance are used,
  • describe the most common ways to build a computer-aided measurement systems,
  • describe the basic principles of spectrum analyzers and how the features of the analyzed signals in the time domain show up in the frequency domain results,
  • be able to compute the standard uncertainty and confidence interval for a combined quantity, following the recommendations of GUM, based on uncertainty information for the different kinds of  quantities contributing to the combined quantity,
  • document and report experimental results orally and in writing,
  • apply the above knowledge and abilities in problem solving and experimental work, both independently and when working in a group.

Literature and preparations

Specific prerequisites *

Completed course corresponding to EI1110 Electrical circuit analysis, extended course.

Active participation in a course offering where the final examination is not yet reported in LADOK is considered equivalent to completion of the course. This applies only to students who are first-time registered for the prerequisite course offering or have both that and the applied-for course offering in their individual study plan.

Recommended prerequisites

Compusory courses in the programme, especially

  • EI1110 Electrical Circuit Analysis, Extended Course
  • EI1220 Electromagnetic Theory E
  • EQ1110 Continuous Time Signals and Systems
  • EQ1120 Discrete Time Signals and Systems
  • SF1901 Probability Theory and Statistics
  • IE1207 Analog Electronics (given in parallel with EK1191, wich works well)

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.

Ethical approach *

  • All members of a group are responsible for the group's work.
  • In any assessment, every student shall honestly disclose any help received and sources used.
  • In an oral assessment, every student shall be able to present and answer questions about the entire assignment and solution.

Supplementary information

The theoretical teaching in each subsection will be concluded with a web-based test or a short written test. The problems in the exam are strongly related to the labs.
