Electronics Laboratory Course
“How do I reduce noise in a measured data signal?”
“How does a lock-in amplifier actually work?”
“Is the measured signal real or am I seeing an artefact?”
“Why is the sampling frequency important for data logging?”
“Why can I measure more precisely with a digital multimeter compared to using an oscilloscope?”
The answers to these questions are important to obtain optimal measurements in a physical experiment – and most importantly, to not chase after any measuring artefacts.
In the electronics lab course of the physics department, students learn the fundamental set of tools used in electronics and a variety of measurement techniques. This includes electronic circuits, different laboratory measurement devices, the construction of a sensitive amplifier, analog-digital conversion and microcontroller programming. The courses ends with an introduction in to computer programs for data logging and the production of your own printed circuits. To this end, the electronics lab course offers high quality lab tools and exciting experiments, notably,
- ECG amplifiers
- Lock-in amplifiers
- Proportional-integral-derivative controller
- Nyquist-Shannon sampling theorem
