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.

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.
