Moc wyjściową Po powinno się liczyć jako: Po=Uwy²/Ro Nie ma jak (albo nie wiem jak) wykonać obliczeń zgodnie z tym wzorem. Wykonywaliśmy tylko pomiary mocy wyjściowej i prądu pobieranego z zasilacza. Przy 4Ω nasze Po wyniosło 0,35W. Właściwie, to Uwe podane jest w wartościach skutecznych (może to wartość między szczytowa odczytana z oscyloskopu) ? Wzmacniacz nie był przesterowany w trakcie pomiarów (zgodnie z katalogiem nie powinien przy tym Uwe) ? Jaką wartość w modelu miał Rf ? Uwe odczytane z oscyloskopu ale w ampiltudzie nie miedzyszczytowe. Wzmacniacz przesterowany nie był(przesterowanie zaczynało się przy większym Uwe). Jeśli chodzi o wartość Rf to nie mam pojęcia. Pomiary wykonywaliśmy miernikiem PWT-5B.Takim jak ten niżej. http://obrazki.elektroda.pl/8379983800_1357511702_thumb.jpg Poniżej wyniki pomiarów i obliczeń:
