Oscilloscope
f(Hz)=1/T(s)
valeur moyenne <u>;Umoy;U/
<u>=A/T = A1-A2 /T

valeur efficasse U= sqrt(<u**2>)

U=sqrt(<u>**2+Ua**2)
Nature:(continu, variable, variable alternatif, signal analogique, 
signal numerique)
Forme:(carre, triangulaire, sinusoidal)
Valeurs extremes:(valeur maximale et minimale)
Periode et frequence

Signal continue analogique 
u = E = -10V
f = 0 
<u> = -10 
U = 10 

Signal alternatif sinusoidale 
<u> = 0
U = Umax/ sqrt2 

Signal alternatif analogique, carre
u=E=10V 
<u> = A/T  = A1-A2 / T = 0V
U = sqrt<u**2>

Signal periodique/variable analogique, forme carre/rectangulaire
<u> = A/T = aT*E / T= aE
U=sqrt<u**2>
 =sqrtaE**2
=sqrta   * E
