Le signal d'entrée utilisé sur le montage (En jaune sur la figure \ref{fig:oscillo1}) est un signal triangulaire d'amplitude \qty{20}{\volt} crête à crête et de fréquence \qty{100}{\hertz}.

On observe sur l'oscillograme (Figure \ref{fig:oscillo1:oscillo}) que $V_{s}$ est en phase avec $V_{e}$. Avec un

signal triangulaire en entrée, on obtient un signal d'allure carré en sortie.

Le signal de sortie est d'amplitude \qty{30}{\volt} c.a.c. . De ces observations, on peut

déduire que le circuit est un comparateur non inverseur simple, ce qui correspond

au shéma et au montage réalisé.

On calcule les valeurs de $V_A^+$ et $V_B^-$ à l'aide d'un pont divisieur de tension ainsi :\\
|
||||
\begin{gather}
|
||||
V_A^+ = V_{CC}\frac{R_3+R_4}{R_2+R_3+R_4}=15\frac{4,7+10}{4,7+10+10}=\qty{8.93}{\volt} \\
|
||||
V_B^-=V_{CC}\frac{R_4}{R_4+R_3+R_2}=15\frac{10}{10+10+4,7}=\qty{6.07}{\volt}
|
||||
\end{gather}
|
||||
De ces valeurs théoriques, on peut espérer des mesures expérimentales proches, dans les marges d'erreur des composants et des appareils de mesures.\\
|
||||
On Utilise alors un multimètre sur les 2 points d'intérêt et on relève les valeurs suivantes :
|
||||
$$V_{a}^{+}=8.95V$$
|
||||
$$V_{B}^{-}=6.07V$$
|
||||
On trouve alors bel et bien les valeurs attendues (avec une erreur de 0,2\%, digne des meilleurs chercheurs du CNRS)

On calcule les valeurs de $V_A^+$ et $V_B^-$ à l'aide d'un pont divisieur de tension ainsi :\\
|
||||
\begin{gather}
|
||||
V_A^+ = V_{CC}\frac{R_3+R_4}{R_2+R_3+R_4}=15\frac{4,7+10}{4,7+10+10}=\qty{8.93}{\volt} \\
|
||||
V_B^-=V_{CC}\frac{R_4}{R_4+R_3+R_2}=15\frac{10}{10+10+4,7}=\qty{6.07}{\volt}
|
||||
\end{gather}
|
||||
De ces valeurs théoriques, on peut espérer des mesures expérimentales proches, dans les marges d'erreur des composants et des appareils de mesures.\\
|
||||
On Utilise alors un multimètre sur les 2 points d'intérêt et on relève les valeurs suivantes :
|
||||
$$V_{a}^{+}=8.95V$$
|
||||
$$V_{B}^{-}=6.07V$$
|
||||
On trouve alors bel et bien les valeurs attendues (avec une erreur de 0,2\%, digne des meilleurs chercheurs du CNRS)
