Communication and Media Engineering (CME)

Signal and System Theory

Empfohlene Vorkenntnisse

• Basic knowledge of mathematics for engineers, in particular complex numbers
• Basic knowledge of communications engineering and signal theory

Lehrform Vorlesung
Lernziele / Kompetenzen

Upon successful completion of this module, the student will be able to:

  • classify and describe signals and linear time-invariant (LTI) systems using methods of signal and system theory.
  • apply the fundamental transformations of continuous-time and discrete-time signals and systems. They can describe and analyse deterministic signals and systems mathematically in both time and frequency domain. In particular, they understand the effects in time domain and frequency domain which are caused by the transition of a continuous-time signal to a discrete-time signal.
  • determine the limits of data compression as well as of data transmission through noisy channels and based on those limits to design basic parameters of a transmission scheme
  • compare the properties of basic channel coding and decoding schemes regarding error detection or correction capabilities
