Abstract

Una secuencia de señal de cambio digital es sugerida, esta secuencia de señal de cambio es realizada como una señal de ruido blanco filtrada de paso alto, previamente digitalizada de una longitud predeterminada T, con una frecuencia de corte de paso alto que se sitúa por encima de la frecuencia en donde la característica de umbral de intensidad acústica en silencio de la escucha humana tiene su sensibilidad más alta, si fuera posible (Figura 5) . La secuencia de señal de cambio es empleada con propósitos de cambio (206), por ejemplo, para el cambio entre dos señales información (201, 207) . Figura 2.
