Abstract

Un sistema de filtrado caracterizado por un método de filtrar selectivamente un tren de impulsos para eliminar aquellos impulsos que difieran en las características de forma de un impulso determinado, sometiendo el tren de impulsos a una serie de operaciones de filtrado y dichas operaciones de filtrado cada una actuando sobre una determinada característica de forma así que las acciones combinadas de estas eliminan los impulsos que difieren en forma del impulso de forma elegida.
