Opiekun Studenckiego Koła Naukowego "Sensor"

Current activity at the University:

Fundamentals of electric circuits (or Circuit Theory) (Podstawy elektrotechniki- lecturer. Two-semester course for Electronics and Telecommunication Students. The course has also exercises and laboratory prepared by the Team. 

  • First semester laboratory exercises:
    • Fundamental electric laws (Kirchhoff's laws, Ohm's law, voltage divider, current divider)
    • Superposition theorem
    • Thevenin & Norton equivalent circuits (maximum power transfer condition)
    • Multiport circuits (matrix R and G description and measure)
    • Nonlinear circuits (circuits with LED, equivalent current-voltage characteristics)
  • Second semester laboratory exercises:
    • Transients in the first order circuits (the laboratory includes approximation of the time domain function)
    • Transients in the second order circuits
    • Non-zero initial conditions
    • Resonant circuits (series and parallel resonances)
    • AC domain analysis
    • Transients in the transmission line (also includes standing wave phenomena)

Fundamental of Signal Processing (Podstawy Przetwarzania Sygnałów) - lecturer. One-semester course for Electronics and Telecommunications Students. The course laboratory contains the following subjects:

  • Fourier series representation of periodic signals
  • Response of linear circuits on the periodic waveforms (includes Laplace transform)
  • Fourier Transform (the Continues Time Fourier Transform)
  • Fundamental parameters: Total Harmonic Distortion (THD), waveform factor (FF), crest factor (CR), Signal-to-Noise Ratio (SNR), noise factor (F)
  • Nonlinear transformation of periodic signals (introduction to modulation)
  • Analog modulations: AM, FM, PM, AM-SC, AM-SSB, ASK (amplitude shift keying), FSK, PSK
  • Sampling theorem (signals representation, Kotelnikow-Shannon-Nyquist theorem, aliasing phenomena)
  • Discrete Time Fourier Transform
