Aim
The aim of the course is to give fundamental knowledge of the electronic components, that a computer will use to communicate with the environments ( interfacing). The aim is also to ratify the professional way for an engineer to work and to ratify the ability to, from given conditions, analyse and construct a system for measurement and steering.

Knowledge and understanding
For a passing grade the student must

• be able to explain the function of basic electronic components, that is used in interfacing techniques

• be able to explain the principles for how to adapt non-electrical quantities to a computer.

Skills and abilities
For a passing grade the student must

• be able to dimension and construct simple electronic circuits of the computers interface

• be able to from given conditions, construct a system for measurement and steering

• be able to analyse an electro-mechanical system and then dimension a convenient bus-system, including sensors and controlers

• be able to show a solution of a interface problem in a technical report

• be able to from given conditions understand and evaluate the information given in manuals and technical documention of different circuits, that are used in interfacing techniques.
