| Course code : | SKRAEP-U01 | ||
| ECTS Credits : | 15 | Status : | Compulsory |
| Revised : | 31/01 2006 | Written : | 19/08 2003 |
| Placement : | 1. semester | Hours per week : | 12 |
| Length : | 1 semester | Teaching Language : | Danish |
| Objective : | To learn some fundamental concepts, theories, components and methods inside the field of analog electronics. Through project work, to ensure practice and absorption, of as many as possible of the topics mentioned under "Main contents". Through project work, to strengthen general engineering qualifications and procedures: Cooperation, time planning, specification, analysis and design, simulation, construction, test, documentation. | ||
| Principal Content : | Concepts and theory: Independent and dependent generators, resistance, capacitance, inductance. Ohms law. Voltage division. Kirchhoff´s current and voltage law. Node- and mesh-equation. Thevenin and Norton equivalent. Power and energy in direct- and single-phase alternating current circuits. Complex frequency ("s"): Transfer function, poles, zeroes, frequency response, Bode plot, natural response, time constant, resonant frequency, quality factor. Elementary inflection theory: Hookes law, inflection of beams, stress and strain. Components and methods: Resistor, capacitor, inductor, operational amplifier. Transducer (strain gauge), diodes and transisters (BJTs). Computer-based math tools. Time- and frequency domain circuit simulation. Time- and frequency domain measurements. | ||
| Teaching method : | Class teaching composed of overview lectures mixed with partly PC-based exercises. The class teaching totals approximately 65% of the scheduled class hours, allocated with 100% in the beginning and 0% in the end of the semester. The teachers will choose 3 exercises, to be compulsory. (Must be handed in and be approved by the teachers) The rest of the time is used for project work in groups. Supervision is given inside the scheduled class hours. From the given project definitions the student is encouraged to go through the engineering (partly iterative) process: Specification*, analysis and design, simulation, construction, test and documentation. The projects are documented by reports and a presentation at the examination (see Remarks). *To ensure proper coverage of "main contents", the "specification" will, to some extent, be given in the project definition handed out by the teacher. | ||
| Recommended prerequisites : | The student should take MATLAB and PSPICE lessons in parallel. | ||
| Relations : | KRAEP is a prerequisite for all the following study modules in the fields of electrotechnology and power electronics. | ||
| Type of examination : | Oral examination based on assignments | ||
| External examiner : | External | ||
| Marking : | Scale of 13 | ||
| Remarks : | In the beginning of the semester the students form their own project groups. The group size should be 3-4 students. Under special circumstances, the teacher may allow other group sizes. If a group member several times fails to fulfil agreements made by the group, the group may recommend an expulsion. If a student doesn"t contributes to the project-work, the teacher may refuse to enter the student for the examination. Examination: At the examination each student is allocated 30 minutes. The examination is a group examination but the marking is individual. The evaluation is based on a general impression of the level achieved by the student relative to the objective of the course. The evaluation is based on the report, the oral performance and the functionality of the project. The group presents the project by giving well-prepared presentations - 15 minutes per student. The group is required to coordinate the presentations in such a way that the major aspects of the project are covered, that the presentations are different and that each individual presentation has a good technical span. After the presentation the supervisors and the external examiner pose questions inspired by the presentations and the report. The questions are a priori individual but may - if found relevant by the supervisors or the external examiner - form the basis of a broader group discussion. During the evaluation by the supervisors and the external examiner, the project group leaves the room. Afterwards the group is summoned and the individual marks are explained. At the exam there is only short time for these explanations - Therefore the students 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. | ||
