Abstract

LA INVENCION SE REFIERE A UN PROCESO PARA LA REDUCCION DE DIAFONIA DE FRECUENCIA DURANTE LA TRANSMISION DE SEÑALES DE AUDIO DIGITALIZADAS. LA DIAFONIA DE FRECUENCIA DEBE SER ESPERADA SIEMPRE QUE LA SEÑAL DE ENTRADA SE DISTRIBUYE A LO LARGO DE BANDAS PARCIALES EN ETAPAS CONECTADAS EN SERIE. DE ACUERDO CON LA INVENCION, LAS SEÑALES A PARTIR DE BANDAS PARCIALES, EN DONDE LOS COMPONENTES DE ESPECTRO DE FRECUENCIAS DETERMINADAS FORMAN COMPONENTES DE SEÑAL, Y SEÑALES A PARTIR DE BANDAS PARCIALES, EN LAS QUE ESTOS COMPONENTES DE ESPECTRO FORMAN COMPONENTES DE DIAFONIA DE FRECUENCIA EN LA BANDA DE PARADA, SON SOMETIDAS A UN PROCESO DE SUMACION DE PESADA. DESPUES DE LA TRANSMISION, LAS SEÑALES DE BANDA PARCIAL SON SOMETIDAS A LA OPERACION INVERSA. EL PROCESO TRABAJA CON RELACION AL PROCESO DE CODIFICACION SELECCIONADO Y ES POR TANTO APLICABLE UNIVERSALMENTE.
