Le monde physique qui nous entoure, varie de fa\u00e7on continue, de fa\u00e7on analogique.\u00a0On peut citer comme exemple, le son, la lumi\u00e8re, les couleurs,\u2026\u00a0Mais quasi tous les syst\u00e8mes qui nous entourent, sont num\u00e9riques\u00a0: les ordinateurs, la t\u00e9l\u00e9vision, les photos, les syst\u00e8mes de communication, les objets connect\u00e9s\u2026<\/p>\n

Tous ces dispositifs fonctionnent de fa\u00e7on discr\u00e8te et non continue.\u00a0Pour passer du monde de l\u2019analogique, au monde du num\u00e9rique, diff\u00e9rent traitements sont n\u00e9cessaires\u00a0: l\u2019\u00e9chantillonnage, la quantification et le codage\u2026<\/p>\n

A partir d\u2019exemples concrets, nous \u00e9tudierons les diff\u00e9rentes \u00e9tapes, et analyserons leurs limites.\u00a0Nous approfondirons ces techniques sur des cas concrets de notre quotidien.<\/p>\n<\/div>\n
