Course offered in summer term 2022:
— Digital signal- and measurement data processing [PHY-EV-V-G]
Modern physical experiments rely at a progressive rate on digital signal processing. Consequently, the realisation of physical experiments as well as the interpretation of resulting measurement data requires an in-depth understanding of the different steps in the signal processing pipeline.
This course (lecture with practical exercises) covers following main topics:
- physical measurement and digital representation of physical data
- sampling and the sampling theorem
- spectral analysis
- discrete-time systems and z-transform
- digital filters
- applications in physical experiments
The course includes practical exercises which are based on two specifically developed boards:
- RTD board: A circuit comprising all steps from an analogue measurement to the digital output. The digital processing is realised around an ATmega 328P microcontroller, identical to the processor used for the Arduino Uno.
- DSMV board: A circuit for real-time digital signal processing. High-quality AD (20bit / 32bit) and DA (20bit) converters are connected to a Cortex-M7 microcontroller (using a Teensy 4.0).
Please register via stud.ip for the course: Link
The lecture will be given in person.
The course will be given in either german or english language.
Course materials are available via stud.ip.
Code is available via GitHub and pypi.

— Non-contact atomic force microscopy [PHY-NCAFM-15]
The imaging and manipulation of single atoms and molecules is nowadays possible by using scanning probe methods, in particular the technique of non-contact atomic force microscopy (NC-AFM) enables the investigation of non-conducting surfaces.
This lecture covers following main topics:
- quantitative atomic force microscopy
- physical description of NC-AFM
- technical aspects of NC-AFM systems
- quantitative force measurements
- examples and current research topics
