Aim
Pedagogic idea:
(General aims for Electronic, systems and signals):
Within "Electronics, systems and signals" several subjects has been integrated with a course in order to emphasise that the subjects are not separate units but rather are like links in a chain. Electronic systems can not be analysed and designed with knowledge in a single academic subject but require a great deal of knowledge of the overview as well as details. The link between system aspects and specific knowledge in a topic is therefore central for "Electronics, systems and signals". It is essential that, although the details in a specific subject are important, they may not hide the whole picture. The student will be trained in relating specific knowledge to the whole picture and to seeing and understanding details in a system and how detailed knowledge is used to build a system.
The student should feel that the subjects are part of an entity and that subjects from different disciplines are interconnected. This is important in order to stimulate creative solutions to multi-disciplinary problems. To support this a number of new pedagogic items have been added. These are described below.

• Developing awareness of common elements - the idea is that a number of common applications connect the different subjects. The applications should further show the student where the specific knowledge is used in a real situation. The application may either be common to all the subjects or to a subset of them. It is natural to use the application from the basic course as one of them.

• "Cross-teaching" (helping students see connections among subjects) - This helps the students see the whole picture and to remember previous studies and at the same time prepare for new topics. This cross-teaching can be a demonstration, lecture, tutorial, laboratory etc. Follow-up with exam questions and laboratory experiments will give this portion of the course extra weight and also ensure that the students remember and use previously gained knowledge.

• Analysis assignments - to further connect the subjects there will be an analysis assignment made in groups and leading to a written and oral report. There are several benefits with this a) teachers are able to offer a stimulating problem early in the program, b) the students are trained in written and oral communication technique, c) the students are trained in having an systems approach, d) there are possibilities for in-depth studies in a topic. The assignment is handed out early in the course and the report must show that the participants have considered knowledge from different subjects and have the ability to connect this knowledge to an entity.
  In all subjects in "electronics, systems and signals" there is a core of basic definitions, methods, and relations. The core is fundamental for the continued education. It is also something that industry expects from an engineer in electronics. An aim is that the student master this core at the end of electronics, system and signals.
  Laboratories are a natural part of electronics, systems and signals. The object is on one hand to expose fundamental parts in the curricula and on the other hand to train the student in experimental laboratory work. The degree of independence will gradually increase and finally pure laboratory parts will be tested in exams.

• have acquired a holistic view of electronics and electrical systems,

• be able to account, in detail, for the internal structure of the building blocks of electronics,

• become familiar with methods and models for analysing electronics, electrical systems and electrical signals.

• have high skills in analysing electronics and electrical systems and knowledge in designing basic circuits and systems,

• be able to move from system level to component level. The student also should be able to move from component level to a system level. The student will further be able to use knowledge from several of the subjects in "electronics, systems and signals" when analysing or solving complex problems,

• have the ability to apply a theoretical approach to a real problem and to mathematically stated electrical models and to see the link between model and reality. In the statement is included the ability to make relevant approximations and to use subject specific definitions and relations,

• be able to measure electrical signals and parameters and to interpret these,
  * have used simulation tools and be able to visualise a problem or a solution with graphs, figures and block diagrams.

• have gained self-esteem and an insight that large parts of the electronic technique is mastered,

• have gained an overview in order to choose an area to focus the rest of the education on,

• have gained awareness of environmental and production aspects for electronics,

• have seen the engineering approach that is used for designing electrical systems

Contents
Course Composition: The course lasts tree semesters and starts with an information lecture (in Swedish) at the first meeting of the first subject: Analogue electronics. The home pages of the different subjects contain specific information on the duration, literature etc. During the entire course you will work on an assignment analysing an analogue circuit.

Literature
See the different subjects.

Code: 0601. Name: Physics of Devices.
Credits: 3. Grading scale: UG. Assessment: Written exam. Contents: Defining semiconductors and charge transport in semiconductors via drift and diffusion. Electrical components like the P-N junction, the bipolar transistor and the MOS transistor. These are covered with respect to potentials, transport mechanisms, inherent capacitors and material parameters. The performance of components regarding frequency limits. Material properties of components, capacitors for example.

Code: 0701. Name: Systems and Signals.
Credits: 4. Grading scale: UG. Assessment: To qualify for a final grade, students must have passed the written examination and the laboratory work. The written examination takes the form of problem solving. Contents: Time and frequency properties of signals are introduced and typical signals are presented. Transforms between time- and frequency domain will be given as well as different methods to calculate the output signal from a digital signal processing system. In the laboratory works, Matlab as well as a real time digital signal processing system (DSP) are used. Various applications are presented, e.g., digital communication system (OFDM) and filtering of signals from the heart (ECG) and the brain (EEG).

Code: 1001. Name: Electrical Measurements.
Credits: 3. Grading scale: UG. Assessment: Continuous examination throughout the laboratory work. Contents: Fundamental concepts like loading of the measurement objects, influence of noise, uncertainty in the results and calibration.

Contents: Project Contents: The main object with this project is to connect the different sub courses in Electronics, Systems and Signals by giving the students a real application to analyse. The project is carried out in student groups of four and is guided by tutors representing the six subcourses. One tutor meeting is held each term. These are compulsory.
