Amplitude — Pour l’article homonyme, voir Amplitude (jeu vidéo). En physique classique, on nomme amplitude la mesure scalaire (une coordonnée) d’un nombre positif caractérisant l’ampleur des variations d une grandeur. Le plus souvent il s agit de … Wikipédia en Français
Amplitude-companded single-sideband modulation — ACSSB (amplitude companded single sideband) is a narrowband modulation method using a single sideband with a pilot tone, allowing an expander in the receiver to restore the amplitude that was severely compressed by the transmitter. This mode… … Wikipedia
Quadrature amplitude modulation — (QAM) (Pronounced IPA|kwa:m) is a modulation scheme which conveys data by changing ( modulating ) the amplitude of two carrier waves. These two waves, usually sinusoids, are out of phase with each other by 90° and are thus called quadrature… … Wikipedia
Secular variations of the planetary orbits — The Secular Variations of the Planetary Orbits (French: Variations Séculaires des Orbites Planétaires, abbreviated as VSOP) is a semi analytic theory describing the long term changes (secular variation) in the orbits of the planets Mercury to… … Wikipedia
