Lab Work
The lab exercises can add up to 4 extra points on the exam. Scoring at least 50% on an exercise gives 0.5 points; 75% or more gives 1 point.
Goal
This lecture is held in English and is mainly aimed at students in our Master's program, who are not yet familiar enough with the German language. The content corresponds to the German lecture "Nachrichtentechnik".
Content
Lecture:
- Signal description: sine signals, Dirac impulse, spectral representation, low-pass signals, band-pass signals
- Linear time-invariant systems
- Analog modulation: amplitude modulation, frequency modulation
- Sampling theorem: sampling theorem for low-pass signals, sampling theorem for band-pass signals, sampling kernels
- Digital modulation: frequency shift keying, phase amplitude modulation
- Stochastic signals: spectral properties, correlation, noise
Exercise:
Problems and examples related to the Fourier transform, analytical signals, linear time invariant systems, simple AM and FM transceivers, sampling and interpolation filters, digital modulation schemes, and stochastic systems.
Exercises
The descriptions of the exercises can be found in the script (section Exercises) and in the exam collection.
