    1. Analyse d’une tension alternative sinusoïdale et périodique

    2. Calcul de l’amplitude Umax Umax est la tension correspondant à un pic. Umax = sv x dv donc dv vaut 3,4 div Si sv = 2 V / div, Umax = 2 x 3,4 = 6,8 V

    3. Calcul de la période La période T est la durée correspondant à un motif élémentaire. T = Sh x dh donc dh = 4 div Si sh = 2 ms / div, T = 2 x 4 = 8 ms T = 0,008 s La période vaut 0,008 s

    4. Calcul de la fréquence

    5. Calcul de la fréquence
