Abstract
UN DEMODULADOR DE SEÑALES DE TIPO RDS RECIBE EN LA ENTRADA UNA ONDA SUBPORTADORA DE UNA SEÑAL RADIODIFUNDIDA MODULADA POR UNA SEÑAL INCIDENTE PORTADORA DE DATOS NUMERICOS, SIENDO ESTA MODULACION UNA MODULACION DE AMPLITUD DE LA SUBPORTADORA POR UNA SEÑAL PERIODICA DE FRECUENCIA PREDETERMINADA Y CUYA AMPLITUD DE LA SEÑAL PERIODICA DEL SEMIPERIODO VARIA RESPECTO DE UN UMBRAL DADO, Y EMITE EN LA SALIDA UNA SEÑAL BINARIA DE DATOS. EL DEMODULADOR DE LA INVENCION COMPRENDE: ENVOLTURA (1), UESTRAS EMITIDAS POR LOS MEDIOS CONVERTIDORES ANALOGICO/NUMERICO SOBRE LA SEÑAL INCIDENTE, . MEMORIZAR LAS SERIES SUCESIVAS DE N MUESTRAS, . ANALIZAR CADA UNA DE ESTAS SERIES SUCESIVAS PARA EMITIR EN LA SALIDA UN VALOR BINARIO EN FUNCION DEL VALOR DE LA MUESTRA CENTRAL DE LA SERIE.
