Abstract
En un sistema de televisión por proyección, está incluida una red compensadora de la reducción gradual en la respuesta del material luminescente azul (QB, RB, RE2A, RE2B, RE3, VBIAS), en el circuito emisor de un transistor (QD) configurado con emisor común, que comprende el amplificador de excitador para el tubo de rayos catódicos del azul. La red compensadora de la reducción gradual de respuesta incluye un divisor de voltaje (RE2A. RE2B), conectado entre el emisor del transistor (QD) configurado con emisor común, y una fuente de un voltaje de excitación (VBIAS), y un segundo transistor (QB), que tiene su base conectada a un punto del divisor de voltaje y su trayectoria de colector-emisor, conectada en serie con un resistor cambiador de ganancia (RB) entre el emisor del transistor configurado con emisor común, y la fuente del voltaje de polarización variable (VBIAS). El divisor de voltaje determina el nivel de corriente de excitación al cual se hace conductor el segundo transistor y, de tal manera, el punto al que se aplica la compensación de reducción gradual de respuesta. El resistor cambiador de ganancia determina la cantidad de compensación.
