Abstract

Un filtro de interpolacion incluye un substractor, un circuito de pasaje y un sumador, en donde el substractor está acondicionado para formar diferencias de muestras originales adyacentes, y el circuito de pasaje pesa las diferencias con un valor predeterminado. El sumador está configurado para a) pasar una muestra original; b) sumar una diferencia pesada a la muestra original; y c) sumar sucesivamente la diferencia pesada a la muestra previamente generada para formar muestras sucesivas.
