Abstract

CIRCUITO DE COMPENSACION DEL NIVEL DE CORRIENTE CONTINUA DE UNA SEÑAL. EL CIRCUITO FUNCIONA EN COMBINACION CON UNA RED DE CONTROL DE GANANCIA DE SEÑAL PARA ASEGURAR QUE EL NIVEL DE CORRIENTE CONTINUA DE UNA SEÑAL ESTA COMPENSADO CORRECTAMENTE PARA PERMANECER SUSTANCIALMENTE CONSTANTE A MEDIDA QUE ES CONTROLADA LA GANANCIA DE LA SEÑAL. SON SUMINISTRADAS POR UN CIRCUITO DE CONTROL DE GANANCIA SEÑALES DE CONTROL DE AMPLIFICADOR Y DE COMPENSACION DE NIVEL DE CONTINUA. ESTA SE MANTIENE POR MEDIO DE UN CIRCUITO ADICIONAL QUE DETECTA LA POLARIZACION DE CORRIENTE CONTINUA DEL AMPLIFICADOR, Y LA POLARIZACION DE CORRIENTE CONTINUA DEL CIRCUITO DE CONTROL DE GANANCIA, Y CORRIGE LAS DESVIACIONES DE LAS POLARIZACIONES CON RESPECTO A UNA RELACION MUTUA PREESTABLECIDA.
