But this requires both that the sensors that are selected enable the transfer of the information required for the application and that the analog-to-digital conversion enable the transfer of the information required for the application to the digital domain. In addition to this, in many cases "feature" extraction or signal processing of the digital version of a sensor signal can be carried out to produce a digital signal (sensor data) that is much easier to interpret, i.e. you "only" enhance information in the signal / data that is of interest for SICPS.
The course will focus on sensors, analog-to-digital converters, quality of measured data and signal processing where we, among other things, highlights the choice of sensors and data collection systems and introduces some robust signal processing methods in the light of the digitization of the industry.
Target group
This course is for professionals who work professionally with programming and development - regardless of industry or sector. You may be in the industry, the IT sector or a larger company in a completely different industry, you may be working in a development department within a company or as an IT consultant.
Content
The course contains the following:
- Sensors for measuring vibrations, force, elongation, speed and associated signal conditioning
- Measurement uncertainty
- Analog-to-digital converter and "Effective Number Of Bits (ENOB)"
- Folding when sampling signals and anti-folding filters
- Fourier transform - Discrete Fourier transform
- Stochastic processes and relevant statistical concepts
- Power density spectrum, Power spectrum and associated systematic and random errors
Practical information
There will be a kick-off and two workshops on site where we learn, among other things to perform measurements on a rotating machine and associated data collection as well as signal analysis with professional equipment. All other lectures are given online and recorded and will later be available online.
The course will be delivered in a flexible way to facilitate the combination of coursework with your ongoing professional commitments.
- The total scope of the course is normally about 100 hours.
- Language of instruction: English.
- The course is free of charge and gives 4 higher education credits.
- Registration can be done continuously until the start of the course.
- Course location is Växjö.
The course may be offered again in the future; it depends on the expressions of interest we receive so if you are interested in the course but is not able to attend this fall please contact us so that we know.

What competences do I need to apply?
Basic qualifications at advanced level in mechanical engineering or equivalent. Candidates with relevant work experience are also welcome to apply. Two years' relevant work experience is considered to correspond to one year of university studies at the bachelor's level, we can validate you competence if needed.
