Abstract

LA FIGURA MUESTRA UN TRAMO DE TRANSMISION DE CONVERSACION. ESTE TRAMO SE GUIA A TRAVES DE UN TELEFONO (11) DE UNA RED (13) PRIVADA A TRAVES DE CENTRALES (14,17) HACIA UN NUDO (19) MOVIL CON ANTENA (20) Y A TRAVES DE UNA UNION (22) DE RADIO HACIA UN TELEFONO (12) MOVIL. PARA ENJUICIAR LA CALIDAD DE TRANSMISION DADA SIRVEN UNA UNIDAD (31) MOVIL Y UNA UNIDAD (32) DE MEDIDA ESTACIONARIA, QUE ESTAN DISPUESTAS EN LAS PROXIMIDADES DE LOS TELEFONOS (11,12). UNA DE LAS UNIDADES (31,32) DE MEDIDA EMITE COMO SEÑAL DE PRUEBA UN MENSAJE DE CONVERSACION HUMANA CON UNA SECUENCIA DADA PREVIAMENTE, QUE SE AJUSTA DE FORMA PREVIA CON UNA MUESTRA DE SINCRONIZACION. DE FORMA RESPECTIVA LA OTRA UNIDAD DE MEDIDA (32,31) RECONOCE LA MUESTRA DE SINCRONIZACION Y DETERMINA CON ELLO EL PUNTO DE TIEMPO DE PRINCIPIO DE LA SECUENCIA SUCESIVA. ESTA FRECUENCIA SE FRACCIONA EN UNA MULTIPLICIDAD DE VALORES INTERMEDIOS RESPECTIVOS, EN DONDE SE FORMAN INTERVALOS DE TIEMPO Y SIENDO DIGITALIZADAS SUS PROPIEDADES DE REGULACION. LA TOTALIDAD DE LOS VALORES INTERMEDIOS SE VALORAN EXCLUSIVAMENTE A TRAVES DE UNA RED NEURONAL DE TAL MODO, QUE EN SU SALIDA SE OBTIENE UNA VALORACION COMPRENSIBLE HUMANA "CON UNA CALIDAD BUENA, MEDIA O MALA". CON ELLO ES IMPORTANTE QUE LA RED NEURONAL ESTE PREPARADA DE FORMA PREVIA PARA DATOS, QUE SON VALORADOS POR LAS PERSONAS DE PRUEBA.
