Abstract

DISPOSITIVO DE CIRCUITO QUE ALTERA EL MARGEN DINAMICO DE SEÑALES DE AUDIO Y DE OTRO TIPO. CONSTA DE UN CIRCUITO SELECTIVO PARA LA FRECUENCIA QUE DETERMINA UNA BANDA DE PASO DE FRECUENCIAS DENTRO DE LA CUAL TIENE LUGAR LA MODIFICACION DEL MARGEN DINAMICO; DE MEDIOS DE MODIFICACION DINAMICO PARA EFECTUAR UNA MODIFICACION DINAMICA PROGRESIVA DE LOS COMPONENTES DE SEÑAL INCLUIDAS EN ESA BANDA DE PASO; DE MEDIOS PARA EFECTUAR UN DESPLAZAMIENTO PROGRESIVO DE LA BANDA DE PASO DE FRECUENCIAS; Y DE UN DISPOSITIVO DE GANANCIA O PERDIDA VARIABLE, INCLUIDO EN LOS MEDIOS DE MODIFICACION DINAMICA, QUE CONTROLA LA ACCION DINAMICA VARIABLE MEDIANTE UN CIRCUITO DE CONTROL. DE APLICACION EN LOS SISTEMAS DE REDUCCION DE RUIDO.
