Lectures
Individual consultations
Experimental work in labs
Project work
Teaching by an expert (lecture or tutorial)

Summary

Students will learn to use all types of measuring devices, from analog to digital to virtual, which they will also try to create. They will be able to measure basic electrical quantities and passive elements using various methods. An integral part of every measurement is also knowledge of the calculation of deviation (error), the uncertainty of the measurement result.

Projects: 10 protocols from measurements according to laboratory exercises. Tests: 10 test questions - in each exercise 1.

Conditions for subject completion

Part-time form (validity from: 2019/2020 Winter semester, validity until: 2023/2024 Summer semester)
Task nameType of taskMax. number of points

Min. number of pointsMax. počet pokusů
Graded credit Graded credit 100  51 3
Mandatory attendence participation: The submitted protocol is worth a maximum of 9 points, the test for the measured task is worth 3 points. A total of 60 points (5 tasks) can be obtained for measured and processed tasks. The remaining 40 points are for separate measurements, which are usually evaluated on a scale of 8 points. Individual measurement is mandatory, it takes 60 minutes, including drafting the protocol. In the distance learning mode, everything will be replaced by activities in the LMS.
