Abstract
DISPOSITIVO DE INTERPOLACION NUMERICA DE SEÑALES. DE ESPECIAL APLICACION EN SISTEMAS DE PROCESAMIENTO NUMERICO DE SEÑALES QUE REQUIERAN UN SOBREMUESTREO. COMPRENDE UN DERIVADOR DE UN ORDEN GENERICO "N" (1) QUE RECIBE LA SEÑAL DE ENTRADA A INTERPOLAR (4) Y GENERA UNA SEÑAL DERIVADA DE ORDEN "N" (5), UN FILTRO INTERPOLADOR DIGITAL (2) QUE RECIBE LA ANTERIOR SEÑAL DERIVADA DE ORDEN "N" (5) Y PRODUCE UNA SEÑAL A SU SALIDA (6) CON UNA FRECUENCIA DE MUESTREO MAYOR QUE LA DE LA SEÑAL PRESENTE A SU ENTRADA, Y FINALMENTE UN INTEGRADOR TAMBIEN DE ORDEN "N" (3) QUE RECIBE LA SEÑAL DE SALIDA (6) DEL FILTRO INTERPOLADOR DIGITAL (2) Y OBTIENE UNA SEÑAL INTEGRADA DEL MISMO ORDEN "N" (7) QUE EQUIVALE A UNA SEÑAL INTERPOLADA DE LA DE ENTRADA AL CITADO DISPOSITIVO.
