Modulets indhold, forløb og pædagogik

Purpose:
Electronic systems never exist in a vacuum; to be useful, they invariably have to interact with their surroundings in one form or another. This interaction commonly takes the form of the electronic system receiving some analog or digital signals through measurement devices or other means. The system then translates these signals into discrete data. The data is then either processed directly by the system itself or communicated to other digital systems, for example a remote computer, where processing can take place. Eventually, the system reacts in response to the result of the processing, generating a new set of analog signals via an appropriate actuator, for instance in the form of a control voltage supplied to an electric motor, speech signals in a mobile telephone system, etc.

The purpose of this semester is to build on and expand the skills and competences within digital and analog electronics acquired on previous semesters, and ensure that the students can apply these skills and competences in a complex reality. Specifically, the aim is that the students obtain an understanding of the interaction between computers and their surroundings via various kinds of sensors and actuators, including modeling and control of physical systems, digital signal processing, as well as communicating systems. Completing this project module thus enables the students to analyze, design and implement systems involving both physical elements and computers
