  • 4 crédits

Responsable(s)

Daniel ROVIRAS

Public et conditions d'accès

Have a level bac + 2 in electronics (BTS, DUT, L2) and basis on mathematics for deterministic and random signals.

Objectifs pédagogiques

The main objective of this course is to give to students a clear view on the characterisation (time and frequency domain, spectrum and probability density function) of deterministic and random signals.
  • Time and frequency representation (Fourier transform and power spectral density),
  • Study of filtering operations (convolution operation)
Sampling and analog to digital conversion

Compétences visées

Upon completion of the subject, students will be able to:
Professional/academic knowledge and skills
  • skills in Fourier analysis and transform, able to go from the time to frequency domain and vice versa,
  • able to characterize deterministic and random signals in the frequency domain (Fourier transform, random processes, autocorrélation function, power spectral density),
  • able to characterize amplitude of random signals (random variables, probability density function, cumulative distribution function),
  • able to study a signal processing chain with addition and multiplication of random signals, able to compute the signal to noise ratio at the output of a signal processing chain,
  • able to characterize narrow band signals (complex envelope, low pass equivalent chain), able to study a transmission system with amplitude modulation,
  • able to use Matlab software for simulations of signal processing studies.
