Abstract

EN UNA REALIZACION, LA INVENCION DESCRIBE UN MULTIPLEXOR/DESPLAZADOR (304) QUE MODIFICA LA ENTRADA DE DEFASAJE (300) SEGUN LA FORMA DE ONDA PARTICULAR DESEADA. LAS PUERTAS DE LOGICA BOOLEANAS (306, 308, 310) MODIFICAN MAS LA SALIDA DEL MULTIPLEXOR/DESPLAZADOR EN BASE A LOS DOS BITS MAS SIGNIFICATIVOS DE LA ENTRADA DE DEFASAJE (300) Y SEGUN LA FORMA DE ONDA PARTICULAR DESEADA. POR ULTIMO, UN MULTIPLICADOR (312) MULTIPLICA LA SALIDA DEL MULTIPLEXOR/DESPLAZADOR POR LA SALIDA DE LAS PUERTAS DE LOGICA BOOLEANA PARA PRODUCIR LA FORMA DE ONDA DESEADA. LA INVENCION PUEDE EMPLEAR BANCOS DE PUERTAS OR EXCLUSIVO Y PUERTAS AND COMO LOGICA BOOLEANA. OTRA REALIZACION DE LA INVENCION DESCRIBE UN METODO DE MODELADO DE ONDAS DONDE UNA FORMA DE ONDA DESEADA SE GENERA A PARTIR DE UNA ENTRADA DE DEFASAJE. LA ENTRADA DE DEFASAJE SE MULTIPLEXA O DESPLAZA EN BASE A LA FORMA DE ONDA PARTICULAR DESEADA. LOS RESULTADOS DE LA MULTIPLEXACION SE MODIFICAN DESPUES CON PUERTAS DE LOGICA BOOLEANA EN BASE A LOS DOS BITS MAS SIGNIFICATIVOS DE LA ENTRADA DE DEFASAJE Y SEGUN LA FORMA DE ONDA PARTICULAR DESEADA. LOS RESULTADOS DE LA MULTIPLEXACION Y DESPLAZAMIENTO Y DE LA LOGICA BOOLEANA SE MULTIPLICAN DESPUES PARA PRODUCIR LA FORMA DE ONDA DESEADA.
