Intended learning outcomes

To provide fundamental knowledge about electronic communication

After passing the course you should be able to

  • Explain important concepts and terminology within the communication field
  • Describe the basic components in a communication system
  • Analyse signals in the domain of time and frequency
  • Explain the difference between digital and analogue signals
  • Describe the function of protocols for Local Area Network (LAN) communication
  • Prepare a LAN for TCP/IP communication
  • Calculate the data rate in a data channel
  • Apply the theory about coding and modulation in a communication system
  • Describe in what way damping and interference influence the signal in a transmission media
  • Describe the appearance of electromagnetic waves and perform a link budget calculation

Course main content

  • Signals in the domain of time and frequency
  • Fourier series and analysis of the square wave signal.
  • Influence on the signal:
    network for limitation of bandwidth, damping, sampling and PCM converting
  • Analogue modulation: amplitude-, frequency- and phase modulation.
  • Methods for digital modulation: ASK,FSK,PSK,BPSK,QPSK,QAM.
  • Data transmission: Bandwidth, media of transmission.
  • Data rate versus modulation rate and bandwidth versus pulse width.
  • Transmission systems
  • Antennas and wave propagation
  • Applications: Wired and wireless systems. (noise, requirement of bandwidth, error detecting and correcting codes)
  • Fundamentals of data communication, standards and the OSI-model
  • Local Area Network: Ethernet and network devices


Good knowledge in mathematics, electric circuits, and electronics.
