Abstract
LA INVENCION SE REFIERE A LA AMPLIFICACION LINEAL DE UNA SEÑAL UTIL, POR MEDIO DE UN AMPLIFICADOR CONECTADO A UNA TENSION DE ALIMENTACION, CUYA SEÑAL UTIL ES MODULADA MEDIANTE UNA SEÑAL MODULADA DE BAJA FRECUENCIA. CON EL FIN DE AUMENTAR EL RENDIMIENTO DEL AMPLIFICADOR, EN LO POSIBLE CON UNA BUENA LINEALIDAD, SE PROPONE SEGUN LA INVENCION, QUE LA TENSION DE ALIMENTACION PARTIENDO DE UN VALOR MINIMO PREDETERMINADO, EL CUAL NO ES REBASADO, EN EL CURSO DEL TIEMPO EN FUNCION DE LA SEÑAL DE MODULACION O DE LA ENVOLVENTE DE LA SEÑAL UTIL, SE SUBORDINE, DE TAL MODO QUE, EL AMPLIFICADOR CON VALORES DE SEÑALES DE AMPLITUDES PEQUEÑAS DE LA SEÑAL DE MODULACION, O DE LA ENVOLVENTE DE LA SEÑAL UTIL, TRABAJE EN LA ZONA LINEAL, Y EN EL CASO DE VALORES DE SEÑALES DE AMPLITUDES MAYORES SE CONTROLE EN LA COMPRESION.
