Learning Outcomes
CB1: Students have demonstrated possession and understanding of knowledge in an area of study that builds on the foundation of general secondary education, and is usually at a level that, while relying on advanced textbooks, also includes some aspects that involve knowledge from the cutting edge of their field of study. CB2: Students are able to apply their knowledge to their work or vocation in a professional manner and possess the competences usually demonstrated through the development and defence of arguments and problem solving within their field of study. CG3: Knowledge of basic and technological subject areas which enable acquisition of new methods and technologies, as well as endowing the technical engineer with the versatility necessary to adapt to any new situation. CG13: Understanding and command of basic concepts of linear systems and related functions and transformers. Electrical circuit theory, electronic circuits, physical principles of semiconductors and logic families, electronic and photonic devices, materials technology and their application in resolving problems characteristic of engineering. ECRT9: Ability to analyze and design combinational and sequential circuits, synchronous and asynchronous circuits, and use of microprocessors and integrated circuits. ETEGISC4: Ability to select circuits, radiofrequency, microwave, radio broadcasting, radio link and radio determination subsystems and systems.  RA1: Knowledge and Understanding. Knowledge and understanding of the general fundamentals of engineering, scientific and mathematical principles, as well as those of their branch or specialty, including some knowledge at the forefront of their field. RA2: Analysis. Graduates will be able to solve engineering problems through an analysis process, identifying the problem, recognising specifications, establishing different methods of resolution, selecting the most appropriate one and implementing it correctly. They must be able to use various methods and recognize the importance of social constraints, human health, safety, the environment, as well as commercial constraints. RA4: Research. Graduates will be able to use appropriate methods to carry out detailed research and studies of technical aspects, commensurate with their level of knowledge. The research involves bibliographic searches, design and execution of experiments, interpretation of data, selection of the best proposal and computer simulation. May require consultation of databases, standards and security procedures. RA5: Applications. Graduates will have the ability to apply their knowledge and understanding to solve problems, conduct research, and design engineering devices or processes. These skills include knowledge, use and limitations of materials, computer models, process engineering, equipment, practical work, technical literature and information sources. They must be aware  of all the implications of engineering practice: ethical, environmental, commercial and industrial.

Learning activities and methodology
Three different teaching/learning activities will be used: theoretical lectures, problem-solving sessions and lab sessions. ECTS credits include in all cases an allotment for personal work and team problem-solving work. THEORETICAL LECTURES (2,48 ECTS) Theoretical lectures will include the use of blackboard and slide material to illustrate main concepts in subject. The explanation of theoretical concepts will be complemented with exercises and problem solution sketches. These lectures will require personal initiative and research plus theoretical study: he/she might be asked to develop particular concepts or apply them to specific problem instances either individually or in the group. PROBLEM SOLVING-SESSIONS AND PROBLEM-SOLVING ASSIGNMENTS (2,64 ECTS) For problem-solving sessions, students will be given problem statements in advance. Problem solving will include common review of solutions and instructor-led correction. These should help ground knowledge and develop the ability to analyze and transmit information relevant to problem-solving. The common review is expected to improve opinion exchange between instructors and students. The last minutes of these classes could be spent taking a short assessment test on the content seen during the week. LABORATORY TESTS (0.86 ECTS) It is intended to carry out two "software" laboratory in computer classroom where the student can simulate the circuits that have been analyzed or designed in the theoretical sessions. With these simulations, students can evaluate the success of the analysis and design techniques learned in class. Individual tutoring sessions are intended to involve specific, clearly defined aspects. Appointments will be managed through the learning management system being used during the course. If required, collective tutoring sessions will be held to provide feedback to the group about the solution and assessment results.
