About this Course#

EG-150 Signals and Systems introduces the mathematical description of signals in the continuous-time and frequency domains. Basic properties of deterministic signals and linear time-invariant systems are defined. The concept of frequency and frequency domain description of signals is introduced using Laplace transform and the Fourier series representation of periodic continuous-time signals. The modelling and simulation of systems using transfer functions and block diagrams is introduced.

Course Content#

  • Signals in time domain: analogue and digital signals, periodic and aperiodic signals, even and odd symmetry signals.

  • Waveforms: sines, cosines, exponentials, steps, rectangular and squares, impulses and ramps.

  • Time domain operations on waveforms: time scaling, time reversal and time shifting.

  • Calculation of waveform properties: energy, power, mean value, R.M.S. value and crest factor.

  • Introduction to systems: basic properties; linear invariant systems; convolution and system response; linear coefficient differential equations.

  • Using the Laplace transform for the representation of signals and systems in the complex frequency domain.

  • The application of the Laplace transforms in electrical circuit analysis.

  • Modelling systems with block diagrams and transfer functions and the concept of feedback.

  • Periodic signals representation in the frequency domain: the trigonometric and exponential Fourier series.

  • The use of MATLAB for signals and systems analysis.
