Number of ECTS credits

5

Mode of study

Not applicable.

Entry knowledge

The subject knowledge on the secondary school level is required.

Rules for evaluation and completion of the course

The course assessment is based on a point system divided between the final exam, which can yield up to 60 points, and the evaluation of laboratory exercises, which account for 40 points. Within the laboratory component, students are assessed on four submitted reports (4 × 5 points), active participation during circuit analysis in the simulation environment (8 points), and a final test evaluating the acquired skills in analog circuit analysis (12 points). 

 

Aims

The aim of the course is to familiarize students with the fundamental concepts of technical diagnostics, explain the differences between physical and functional diagnostic approaches, clarify the issue of error sources that may arise during measurements and how to prevent them, introduce methods for testing basic electrical blocks, present the principles of built‑in self‑test methods and the JTAG interface, and provide insight into circuit design practices that support easy diagnosability. After successfully completing the course, the student will be familiar with the basic terminology used in the field of technical diagnostics. They understand the difference between physical and functional diagnostic methods. They know the possible causes of errors that occur when measuring electrical circuits and how to avoid them. They understand the principles on which the JTAG test interface is based. They can list the key design guidelines for electronic systems to ensure good diagnosability.
