Capacité d'un signal

La capacité d'un signal est la vitesse maximum à laquelle des informations peuvent être envoyées sur un canal.
Nous avons donc besoin du rapport signal/bruit de la liaison.

Théorème de Shannon :


  • C = Capacité en bits/sec.
  • B = Bande de 3100Hz
    (de 300Hz à 3400Hz).
  • S/N = Rapport signal/bruit => 10 logPs/N.
  • PS = Puissance du signal.
  • N = bruit.
