 <\/p>\n

Un signal utile peut \u00eatre modifi\u00e9 par la superposition d\u2019une perturbation, le bruit.<\/strong> <\/span><\/p>\n

 <\/p>\n

\"\"<\/p>\n

\n

Le bruit peut \u00eatre de plusieurs natures :<\/span><\/p>\n

    \n
  1. \n
    Electrostatique<\/div>\n<\/li>\n
  2. \n
    Electromagn\u00e9tique<\/div>\n<\/li>\n
  3. \n
    Magn\u00e9tique<\/div>\n<\/li>\n<\/ol>\n<\/div>\n
    \n
    \n

    1 ) Electrostatique<\/span><\/h4>\n

    Le bruit \u00e9lectrostatique est g\u00e9n\u00e9ralement d\u00fb \u00e0 un effet de couplage capacitif, entre 2 pistes par exemple.<\/p>\n

    \"\"<\/p>\n

    \n

    Le signal 1 devient du bruit pour le signal 2 et inversement.<\/p>\n<\/div>\n

    \n

    \u00a02 ) Electromagn\u00e9tique<\/span><\/h4>\n<\/div>\n<\/form>\n
    \n

    Le bruit \u00e9lectromagn\u00e9tique est g\u00e9n\u00e9ralement d\u00fb \u00e0 une piste ou un c\u00e2ble qui r\u00e9agit comme une antenne.<\/p>\n<\/div>\n

    3 ) Magn\u00e9tique<\/span><\/h4>\n
    \n

    Le bruit magn\u00e9tique est g\u00e9n\u00e9ralement d\u00fb \u00e0 une piste qui r\u00e9agit comme une inductance.<\/p>\n<\/div>\n

    \n\n

    4 ) Les principales sources de bruit<\/span><\/h4>\n<\/form>\n<\/div>\n
    \n
      \n
    • \n
      Le secteur 50Hz<\/div>\n<\/li>\n
    • \n
      Les ondes radio : t\u00e9l\u00e9vision, wifi, t\u00e9l\u00e9phone etc<\/div>\n<\/li>\n
    • \n
      Les appareils utilisant des alimentations \u00e0 d\u00e9coupage<\/div>\n<\/li>\n<\/ul>\n<\/div>\n
      \n\n

      5 )\u00a0 Les solutions<\/span><\/h4>\n

      Le mode diff\u00e9rentiel<\/strong><\/span><\/p>\n

      \n

      S’il y a perturbation, elle sera la m\u00eame sur les 2 fils et vu que c’est une tension diff\u00e9rentielle toutes perturbations communes aux 2 fils est supprim\u00e9es.<\/p>\n<\/div>\n<\/form>\n<\/div>\n

      \u00a0\"\"<\/div>\n
      \n\n
      <\/div>\n<\/form>\n<\/div>\n

      Le blindage<\/span><\/h4>\n
      \n

      On intercale la masse entre le signal \u00e0 prot\u00e9ger et le bruit. Le couplage capacitif ne se fera plus avec le signal mais avec la masse.<\/p>\n<\/div>\n

      \n

      \"\"<\/p>\n

      Dans le cas des circuits doubles faces, on utilise aussi une grille de masse \u00e0 la place du plan de masse pour diminuer l’effet capacitif entre les faces.<\/p>\n

      \"\"<\/p>\n

      \n

      Le champ \u00e9lectrique est r\u00e9fl\u00e9chit sur une surface conductrice et le champ magn\u00e9tique absorb\u00e9.<\/p>\n<\/div>\n

      \n\n
      <\/div>\n<\/form>\n<\/div>\n

      Le tressage<\/span><\/h4>\n
      \n

      La tension induite, par un champ magn\u00e9tique, aux bornes d’une spire est proportionnelle \u00e0 la surface de cette spire. C’est pour cette raison qu’on tresse les conducteurs pour diminuer cette surface et ainsi diminuer la bruit.<\/p>\n
