This class introduces student engineers to the concept of a signal's duality in terms of its frequency and temporal characteristics and defines the fundamental signal treatment : filtering.

- Signal definitions
- Energy and power
- Noise
- Units of Measure : decibels, adbsolute and relative values, practical measurements, signal to noise ratios
- Periodic signals (Fourier)
- Frequency analysis
- Filters

Individual evaluation : coefficient 2
Note of synthesis (report of practical works about the temporal analysis and spectrum analysis) : coefficient 1
