Abstract

GENERADOR DE CONJUNTOS DE COEFICIENTES DE PONDERACION DE FILTRO DE DATOS MUESTREADOS.EL APARATO OPERA A PARTIR DE UN UNICO CONJUNTO ALMACENADO DE COEFICIENTES DE PONDERACION. ESTOS COEFICIENTES, QUE DEFINEN LA RESPUESTA DEL FILTRO, DETERMINAN TAMBIEN LA RESPUESTA DE IMPULSOS DEL FILTRO EN EL DOMINIO DEL TIEMPO. EL CAMBIO DE ESCALA DE LA RESPUESTA DE FRECUENCIA DEL FILTRO SE TRADUCE EN UN CAMBIO DE ESCALA INVERSO DE LA RESPUESTA DE IMPULSOS, Y VICEVERSA. POR CONSIGUIENTE, PUEDEN MODIFICARSE LOS VALORES DE COEFICIENTES EN PUNTOS DE MUESTRA INTERMEDIOS SOBRE LA CURVA DE RESPUESTA DE IMPULSOS SELECCIONADA, PARA ALTERAR LA RESPUESTA DEL FILTRO EN FUNCION DE LA FRECUENCIA.
