ELI1100 Electronics Course description

The course provides an introduction to the field of electronics. The main focus is analog electronics with an introduction to electrical systems, sensors and actuators. Systems are analyzed with frequency analysis and transient analysis. The main component of electrical systems amplifiers is presented and controlled with feedback, this is especially evident in the course when working with the operational amplifier. The last part of the subject is semiconductor technology with the construction of semiconductors. Diodes as simple pn-junctions are presented before bipolar transistors and field effect transistors MOSFET and JFET.

• has knwoledge about amplifiers and how to analyse these
• has general knowledge about control of electronic systems and especially feedback systems
• has knowledge about construction of semiconductors and how they work
• know how to use diodes and transistors

Skills

The student can

• analyze transient conditions in second-order RLC circuits
• design amplifier based on feedback systems
• understand and use circuit diagrams and perform error checking
• discuss a circuit solution and explain how it works
• use supplier manuals and data sheets

General competence

The studentcan

• analyze a problem and specify a solution methodology
• explain and discuss different choices of solution method
• account for the historical development in the field of electronics

Lectures and exercises including use of MATLAB

Mandatory deliveries:

4 exercises

1 ultrasound lab

1 diagnostic group work

Each task should take about 5 hours of work

Individual written exam 3 hours.

The result of the exam can be appealed.

In the event of a resit or rescheduled exam, an oral examination may be used instead. In case an oral exam is used, the examination result cannot be appealed.

Approved calculator

Graded scale A-F

One internal sensor. External sensor is used regularly.

In case of a continuation exam, the exam can be oral with two internal sensors.
