Abstract

LA CANTIDAD DE DATOS GENERADOS EN EL PROCESO DE REGISTRO DE MUESTRAS DE AUDIENCIA, INCLUSO CORTAS, POR MEDIO DE UN MONITOR (1) PUEDE REDUCIRSE CONSIDERABLEMENTE EFECTUANDO UNA NORMALIZACION A UNA GAMA DE VALORES D Y UNA POSTERIOR CORRELACION NO LINEAL A UNA SEGUNDA GAMA PREFERIBLEMENTE MAS PEQUEÑA DE VALORES W. EL RESULTADO PUEDE ALMACENARSE EN UNA MEMORIA ELECTRONICA. OTRAS MEDIDAS PREFERIDAS SON LA DIVISION DE LAS MUESTRAS DE AUDIENCIA EN, POR EJEMPLO, 6 SEÑALES, CADA UNA DE LAS CUALES CONTIENE UNA BANDA DE FRECUENCIAS RESPECTIVA DE LA SEÑAL ORIGINAL Y LA CONVERSION DE LOS VALORES DE LA AMPLITUD ORIGINALES EN VALORES DE VARIACION DE ENERGIA CON UN FILTRADO SIMULTANEO DE PASO BAJO. PREFERIBLEMENTE, TODOS LOS PASOS DE PROCESAMIENTO CITADOS SE REALIZAN POR UN PROCESADOR DE SEÑALES (9). ASI PUEDE OBTENERSE, CON LA TECNOLOGIA MODERNA, UN TIEMPO DE REGISTRO CONTINUO DE HASTA 14 DIAS MEDIANTE UN MONITOR EN LA FORMA DE UN RELOJ DE PULSERA.
