Learning outcomes
The subject is aimed at gaining knowledge about diagnostic methods in electronics, about its theoretical basis and about the technical support for diagnostics. The particular emphasis is aimed at digital circuits and at very large scale integrated circuits. Students will acquire knowledge about diagnostic approaches oriented at typical failures in electronics, about life tests, and about reliability evaluation for components and assemblies. The subject covers the technological aspect of diagnostics as well.
After completion of this subject, students are oriented in the field of diagnostics and testing in electronics. They are able to use basic diagnostic approaches and methods, and develop them further providing to work in production or development branch.
The prerequisite for this subject is a successful completion of subjects in physics, in electrical engineering and in electronic.

Assessment methods and criteria
Grade (Using a grade system), Oral examination, Analysis of the student's performance, Preparation of a presentation

Students have to pass laboratory excercises and submit relevant protocols, or in case of individual study, the student in question has to complete a thematic project. The subject is concluded with a viva based on a random choice of two themes and a written preparation.The result of a subject examination is expressed on a six-point scale: A "výborně" (i.e. "excellent"), B "velmi dobře" (i.e. "very good"), C "dobře" (i.e. "good"), D "uspokojivě" (i.e. "satisfactory"), E "dostatečně" (i.e. "sufficient"), F "nedostatečně" (i.e. "fail").
