gain = 20 log T

G(0) = 20 log T(0)
Go = valeur la plus haute

To = 10 puissance G0/20

T = Vs/Ve
Vs= T0*Ve
Ve = Vs / T0

Vs = tension sortie
Ve = tension entree

S(infini) = T0*E
T0 = S(infini)/ E

S(infini) = valeur finale
T0 = amplification statique
E  = echelon d'amplitude 

temps réponse 5% = coeff amor
a 0,7 donc phenomene resonnance
si graphique en frequence

w0 = pulsation de coupure

gain statique = gain continue

frequence coupure /freq basse
= Gstatique -3dB

f(0)= frequence centrale = la
plus haute

largeur basse bande

delta w : fHaute - fBasse

Q =coeffe de qualité 
w0 / delta w
Q = 1/R * rac de L/C

R/l = w0 / Q
1/LC = w0 ^2

dépassement : 
(Smax - S infini ) / S infini

(-pi*m) / e rac 1-m^2
