The teaching methodology will include: - Theoretical-practical classes where the knowledge that students must acquire will be presented. The students will have at their disposal the class notes and will have basic reference texts to facilitate the follow-up of the classes and the development of the subsequent work. - Problem classes, in which the problems proposed to the students are developed and discussed. - Laboratory practices where the student analyses, implements and measures characteristic parameters of electronic circuits of real application, using instrumentation and measurement techniques in the laboratory. - Tutorials. Individual assistance (individual tutorials) or group (collective tutorials) to students by the teacher. - Individual or group work of the student Note: Use of Artificial Intelligence tools is selectively allowed in this subject. The teacher may indicate a list of assignments and exercises that the student may carry out using AI tools, specifying how they should be used, and how the student should describe the use he/she has made of them. If the use of AI by the student gives rise to academic fraud by falsifying the results of an exam or work required to accredit academic performance, the provisions of the Carlos III University of Madrid Regulations for the partial development of Law 3/2022, of 24 February, on university coexistence will be applied.
