| Målsætning : | Purpose: To learn some fundamental concepts, theories, components and methods inside the field of analog electronics and mathematical modeling, including analogies between electrical and technical systems. Through project work, to ensure practice and absorption, of as many as possible of the topics mentioned under “Principal Content”. Through project work, to strengthen general engineering qualifications and procedures: Cooperation, time planning, specification, analysis and design, mathematical modeling, simulation, verification of models, hardware construction, test, documentation. Learning outcomes: The student must be able to: 1. Use concepts, theory, components and methods introduced in the course. 2. Develop and use mathematical models of technical systems as introduced in the course. 3. Design, calculate, analyze, model, simulate, construct and test analog hardware. 4. Plan, specify, cooperate, document and use relevant engineering terms and language. 5. Relate specifications, calculations, simulations and measurements and draw clear and relevant conclusions. 6. Hypothesize the reasons for differences between simulated and actual results and discuss the hypothesis from relevant theory or from relevant simulations and tests. |

| Undervisningsform : | Class teaching composed of overview lectures mixed with partly PC-based exercises. The class teaching totals ~60% of the scheduled class hours, allocated with 75% in the beginning, 50% in the 10th to the 14th semester week and 0% in the end of the semester. Supervision is given inside the scheduled class hours. From a given project definition the student is encouraged to go through the engineering (partly iterative) process: Specification*, analysis and design, modeling, simulation, verification, design, test and documentation. Assignments and Projects are documented by one or more records of answers or reports and a presentation at the examination (see "Exam"). *To ensure proper coverage of "main contents", the "specification" will, to some extent, be given in the project definition handed out by the teacher. |

| Bemærkninger : | - Oral examination based on a presentation and project reports. - 7 step scale Grades are given as follows from a general impression and are based on the reports, the presentation, the demonstration (the functionality of constructed analog hardware) and the individual exam: 02 For a minimum of basic knowledge and routine corresponding to the learning outcomes point 1 and 2. 7 For knowledge, routine and behavior corresponding to the learning outcomes point 1 to 4. 12 For knowledge, routine, behavior and reflective skills corresponding to all the learning outcomes point 1 to 6. - Exam : Oral examination based on group-made products ( Reports and presentation including demonstration of constructed analog hardware) Remarks : The students must carry out a small number of exercises and projects. The reports must be approved to enter for the examination. In the beginning of the semester the students form their own project groups. The group size should be 3-5 students. Under special circumstances, the teacher may allow smaller group sizes. A supervisor will be assigned to each group. The supervisor follows the group and is in charge as examiner. If more teachers are involved in the course, the groups are divided among the teachers, by the teachers. Students that have not formed a group, before a deadline set by the teacher, are considered to be inactive in the groupwork and may be refused to enter for the examination. If a group member several times fails to fulfil agreements made by the group, the group may recommend exclusion. If a student doesn"t contribute to the project-work, the teacher may refuse to enter the student for the examination. On the same day as the examination, before the examination, the group must together present the exercises and projects, including a demonstration of constructed analog hardware. Each student is allocated 20 minutes for their presentation. The group is required to coordinate the presentations in such a way that the major aspects of the exercises and projects are covered, that the presentations are different and that each individual presentation has a good technical span. At the presentation the external censor and the supervisor will be the audience. The supervisor takes notes for the examination. Examination: Each student is allocated 15 minutes (all in all). The examination is individual. The supervisor and the external examiner pose questions inspired by the presentation, but reports may also be discussed. After the examination students, who wish so, may request (by email) a consultation after the exam, where the exam and the project report can be discussed with the supervisor. At this consultation, students that have not passed the exam will be guided on how to work purposeful towards passing a new exam. The consultation will normally take place in the beginning of the following semester. |
