CHE SIGNIFICA PREAMPLIFIER IN INGLESE
preamplificatore
Un preamplificatore è un amplificatore elettronico che prepara un piccolo segnale elettrico per ulteriori amplificazioni o elaborazioni. Un preamplificatore viene spesso posizionato vicino al sensore per ridurre gli effetti del rumore e delle interferenze. Viene usato per aumentare la forza del segnale per guidare il cavo allo strumento principale senza degradare significativamente il rapporto segnale / rumore. La prestazione acustica di un preamplificatore è fondamentale; Secondo la formula di Friis, quando il guadagno del preamplificatore è elevato, l'SNR del segnale finale è determinato dal SNR del segnale di ingresso e dalla figura di rumore del preamplificatore. In un sistema audio domestico, il termine 'preamplificatore' può talvolta essere usato per descrivere l'apparecchiatura che passa semplicemente tra diverse sorgenti di livello di linea e applica un controllo del volume, in modo che non possa essere coinvolta alcuna amplificazione effettiva. In un sistema audio, il secondo amplificatore è in genere un amplificatore di potenza. Il preamplificatore fornisce guadagno di tensione ma non guadagno corrente significativo. L'amplificatore di potenza fornisce la corrente più elevata necessaria per azionare gli altoparlanti.
definizione di preamplifier nel dizionario inglese
La definizione di preamplificatore nel dizionario è un amplificatore elettronico utilizzato per migliorare il rapporto segnale / rumore di un dispositivo elettronico. Aumenta un segnale di basso livello a un livello intermedio prima che venga trasmesso all'amplificatore principale A volte abbreviato in: preamplificatore.
