4. Random signals (stochastic processes):
pdf, stationarity, second-order description (mean, autocorrelation function), cyclostationarity, power spectral density, cross-correlation function und cross-power spectral density, effects of linear systems, time averages und ergodicity, discrete-time random signals, special random signals, complex random signals and circular symmetry, whitening filter, innovations filter, Wold decomposition, AR, MA and ARMA processes, LMMSE estimation (Wiener filter), linear prediction
The theory presented in the lectures is illustrated by problems in exercise classes.
The problem sets and more information will be available online in TWUEL.
Students who are admitted may register for the written exam via TISS. There are typically four exam dates per year (see examination dates). Please de-register in TISS or via email in case you cannot attend an exam you registered for.
The written exam consists of four problems and lasts three hours. As of now, we are planning to make an exam at the end of the semester on site at the university. For this exam a copy of the lecture notes will be provided during the exam. Additionally, a calculator may be used. The use of other documents or electronic devices is not permitted.
As it is possible that the situation changes throughout the semester, we might adapt the modalities of the exam.
The result of the written exam will be sent to your generic student address (e<matriculation_number>@student.tuwien.ac.at) in a signed email and uploaded to TUWEL.
Specific questions regarding exam problems and exercise problems can be discussed during office hours. Due to the special situation with COVID-19 office hours are online and by appointment.
