Abstract
LA PRESENTE INVENCION SE REFIERE A UN APARATO QUE TIENE UN AMPLIFICADOR CONTROLADO DE VOLTAJE (14) EN EL QUE LA GANANCIA DEL AMPLIFICADOR SE DETERMINA EN RESPUESTA AL NIVEL DE UNA SEÑAL DE CONTROL EN UN TERMINAL DE ENTRADA (16). SE USA UNA PRIMERA VELOCIDAD DE CAMBIO PARA PRODUCIR UN CAMBIO DE GANANCIA DESDE UN NIVEL DE SEÑAL BAJO HASTA UN NIVEL DE SEÑAL MAYOR, Y UNA SEGUNDA VELOCIDAD DE CAMBIO SE USA PARA PRODUCIR UN CAMBIO DESDE UN NIVEL DE SEÑAL ALTO HASTA UN NIVEL DE SEÑAL MAS BAJO, SIENDO LA SEGUNDA VELOCIDAD MAS RAPIDA QUE LA PRIMERA VELOCIDAD.
