c. Étape 2 : calcul des termes de la grandeur de sortie

Comportement en continu

La valeur moyenne `S_0` de la grandeur de sortie est calculée à partir du comportement du dispositif en continu et de la valeur moyenne `E_0` de la grandeur d'entrée.

Comportement en sinusoïdal

Le comportement du dispositif linéaire en régime sinusoïdal étant connu, l'harmonique de rang `n` du signal de sortie, noté `s_n(t)`, est calculé à partir de l’harmonique de rang `n` du signal d’entrée `e_n(t)`.
