|
|
|
Ve čtyřech různých zapojeních můžeme porovnat vlastnosti jednotlivých zesilovačů
|
|
|
|
a závislosti výstupního napětí $U_2$ při změně $U_1$.\\
|
|
|
|
\newline
|
|
|
|
Můžeme pozorovat jednotlivé náběhy napětí, dané úseky až do krajních mezí k~bodům
|
|
|
|
nasycení. Taktéž můžeme pozorovat závislosti při změnách odporů.\\
|
|
|
|
Výsledné zesílení můžeme jednoduše spočítat nebo změřit.\\
|
|
|
|
\newline
|
|
|
|
Můžeme pozorovat, že narozdíl od neinvertujícího zesilovače, invertující má
|
|
|
|
větší rozsah vstupního napětí $U_1$ než se dostane do stavu nasycení a to přibližně o 2V.
