Credits: 9. Grading scale: TH. Course coordinator: Bertil Larsson, Elektrovetenskap. Parts: 4. Further information: The course starts with lectures only, during second autumn semester (LP2). During spring semesters we have lectures, tutorials and laboratories according to: Lectures 56h, project work 60h, tutorials 42h and laboratories 28h. Work load outside the plan is predicted to 150h.

Aim
Pedagogic idea: The curriculum is built on a real application (e.g. a DVD player, mobile phone, X2000 train) e.g. every course item is well covered in the application. The course will give an over-all view and show the signal path through the system.

A compulsory series of lectures and a project work starts the course. The object of these are to inspire and to introduce the course, practice communication skills as well as give a general view of the E-program and the attached departments. The technical report of the project work will initially be reviewed by the students themselves (another group) before the lecturers marking.

Description of course objects and knowledge aims is of great importance to increase the students possibility to take responsibility for their learning. It should be clear that acquired knowledge in this course is mandatory for continued studies at the E-program. The course will have opportunity to make real experiences, contemplation/observation, abstract thinking and practical action. This idea is common for lectures, tutorials, hand-ins and laboratories. The way to achieve this is to have discussions, demonstrations or short laboratory experiments during lectures an tutorials. It is vital that theory, applications and practice are closely coupled. The hand-ins are a part of the continues examination. Rapid feedback to the student is important.

One of the hand-ins is organised as a realisation of a circuit done by each student on his/hers own. To make this possible and to encourage to experimentation a lab kit is part of the literature. There should also be an open laboratory. Another aim for the lab kit is to enhance the interest for electronics. To ensure that the students actively participate in the course a written exam is held at mid term. It is aimed at knowledge, understanding and application of the covered parts. The marking is mainly done by the students themselves. The benefit of this is that there is possibility for discussion, deeper insight in your own knowledge and the fact that this will be a review so far.

Knowledge aims: The student have acquired an over-all view and will be able to show skills in electronic systems, e.g. the design consisting of schematics, components, sources and loads. He/she will have deep knowledge in network theory and basics of the nature of signals in time and frequency. The student will also know the structure of a technical report and has acquired knowledge and methods for seeking information. Knowledge in the structure of the E-program, the work in a department and the advanced courses given by the departments of the E-program

Skill aims: The student must show practical skills in the laboratory, both in design and in measurement activities. A method of finding errors in a circuit is achieved. He/she will be able to analyse circuit diagrams both with nodal analysis and in a circuit simulator. The student will also have the ability to write a technical report of high quality, seek information and work in a team.

Attitude aims: The student will acquire an increased interest for electronics and a vision of possible work situations for an E-engineer. He/she will have a personal relation to people at a department, which minimizes the distance between lecturers/departments and students. Acquired self esteem to manage different circuit analyses and in handling oscilloscopes, multimeters. The student will see the value of acquired knowledge and its use in future courses. The student will take personal responsibility for acquiring knowledge.

Contents
General knowledge and over-all view of electrical systems: The initial lectures will cover items like how to write a report, use of computers, seeking information, ethics, environment/life cycle analysis, the function of the technical parts in an application and finally the invited speakers view of being an E-engineer.

Project work and writing a report: The project work, done in groups of four, will cover a topic related to a specific application (for instance a DVD player, a mobile phone, a X2000-train). This topic is related to a department. The group will present a technical report related to the topic by collecting information and interview people at the department. The technical reports will be compiled and published. This material will then be used during the course.

Signals: Analog and sampled signals. The time and frequency dependence of signals. Input/output relations. Transfer function. Impulse response, convolution and the Fourier transform.

Analysis of electrical circuits: Current, voltage, current sources, voltage sources, resistors Kirchhoffs laws. Nodal equations, nodal analysis. Two-pole equivalents, Capacitors, inductors, nonlinear components, transformers, mutual inductance, impedance, admittance. jw-method, Laplace transform. Time and frequency dependence of circuits. Feedback.

Measurement technique: The function generator, the oscilloscope and the multimeter.

Applications: Signal and power matching. Amplifiers, analog to digital converters, simple power supplies. Basic analog filters, poles and zeros. Bode plots
