Abstract

EN UNA DISPOSICION DE CONEXION PARA ELABORACION DIGITAL DE SEÑALES AUDIO EN RECEPTORES DE RADIODIFUSION PREFERENTEMENTE EN UN RADIO DE AUTO, PASAN LAS SEÑALES AUDIO A UN FILTRO DIGITAL CONFORMADO COMO AJUSTADOR DE SONIDO, CUYO PASO DE FRECUENCIA ES CONTROLABLE CON COEFICIENTES ADMITIDOS CUYA MASA DE TRANSMISION ES CONTROLABLE CON NIVELES DE AJUSTE ADMITIDOS. EN EL CASO DE UNA ELEVACION DE LA FRECUENCIA ALTA Y BAJA SE REDUCE CORRESPONDIENTEMENTE LA MASA DE TRANSMISION DEL FILTRO A UNA FRECUENCIA MEDIA. LA REDUCCION SE COMPENSA CON EL AJUSTADOR DE SONIDO. EL AJUSTADOR DE SONIDO PUEDE PRESENTAR UNA PARTE ANALOGA Y UNA PARTE DIGITAL.
