QUÉ SIGNIFICA PREAMPLIFIER EN INGLÉS
Preamplificador
Un preamplificador es un amplificador electrónico que prepara una pequeña señal eléctrica para una mayor amplificación o procesamiento. Un preamplificador se coloca a menudo cerca del sensor para reducir los efectos del ruido y de la interferencia. Se utiliza para aumentar la intensidad de la señal para conducir el cable al instrumento principal sin degradar significativamente la relación señal-ruido. El rendimiento del ruido de un preamplificador es crítico; Según la fórmula de Friis, cuando la ganancia del preamplificador es alta, la SNR de la señal final es determinada por la SNR de la señal de entrada y la cifra de ruido del preamplificador. En un sistema de audio doméstico, el término "preamplificador" a veces se puede usar para describir equipos que simplemente cambian entre diferentes fuentes de nivel de línea y aplican un control de volumen, de manera que no puede estar implicada ninguna amplificación real. En un sistema de audio, el segundo amplificador es típicamente un amplificador de potencia. El preamplificador proporciona una ganancia de tensión pero no una ganancia de corriente significativa. El amplificador de potencia proporciona la corriente más alta necesaria para accionar altavoces.
definición de preamplifier en el diccionario inglés
La definición de preamplificador en el diccionario es un amplificador electrónico utilizado para mejorar la relación señal / ruido de un dispositivo electrónico. Aumenta una señal de bajo nivel a un nivel intermedio antes de que se transmita al amplificador principal A veces acortado a: preamplificador.
