Abstract
LA INVENCION NARRA UN METODO Y UNA DISPOSICION DE UN CIRCUITO PARA AJUSTAR EL NIVEL Y/O EL MARGEN DINAMICO DE UNA SEÑAL DE AUDIO EN UN SISTEMA DE TRANSMISION Y PARTICULARMENTE EN UNA ESTACION MOVIL. DE ACUERDO CON LA INVENCION, EL NIVEL DE RUIDO ACUSTICO EN EL AMBIENTE DE UN TERMINAL(10, 12), Y EL NIVEL DE RUIDO DE UNA SEÑAL RECIBIDA SE MIDEN(123) Y EL NIVEL Y/O EL MARGEN DINAMICO DE LA SEÑAL REPRODUCIDA SE AJUSTA(121,122) DE ACUERDO A LOS RESULTADOS DE DICHAS MEDIDAS. LA SOLUCION DE ACUERDO CON LA INVENCION AYUDA A REDUCIR EL EFECTO DEL RUIDO EN LA SEÑAL TRANSMITIDA EN EL CANAL DE TRANSMISION(11) Y DEL RUIDO ACUSTICO EN EL ENTORNO DEL TERMINAL(12) EN LA CLARIDAD DE LA SEÑAL REPRODUCIDA.
