Subject description


  • Enrolment in semester.

Content (Syllabus outline):

  • Fundamentals of communication: information, communication channel. Redundancy and irrelevance of information signals.
  • Random signals and noise: probability, random variable, probability density function; stochastic process, autocorrelation, power density spectrum.
  • Properties of common information signals: sound signals, video, data.
  • Digital transmission of analogue signals: sampling, quantization, coding; reconstruction, origins of signal degradation.
  • Physical transmission media: wireless medium, optical fibre, transmission line. Fundamentals of lossy transmission lines: attenuation, dispersion. Wave phenomena on short lines.
  • Wired transmission of analogue signals: equalization, noise accumulation.
  • Baseband pulse signaling: line codes, intersymbol interference, bit error rate.
  • Bandpass signaling: continuous wave modulations. Linear and angle modulation schemes, principles of modulation and demodulation, superheterodyne receiver.
  • Digital signal modulations: OOK, FSK, PSK, QAM.

Objectives and competences:
