Abstract
The category of "Laboratory Courses, Projects, Seminars" includes courses and laboratories in various formats designed to impart practical knowledge and skills. Moreover, these classes encourage independent experimentation and design, allow for explorative learning and teach the methodology of project work.
Objective
This P&S is about the design and operation of an optical infrared audio transmission system. For this purpose, we familiarize ourselves with important laboratory and measurement equipment (oscilloscope, spectrum analyzer) and measurement methods (record frequency response, S/N ratio, nonlinear interference). The influence of modulation to suppress interference will be investigated in experiments. Each student builds an infrared transmitter and receiver. During assembly, we gain hands-on experience with soldering conventional and SMD components. The finished circuits are tested and tuned and can be taken home afterwards.
