Abstract

Filtro digital para filtrar una señal digital que comprende palabras digitales, que comprende: medios (14, 16) de definición de ventana para definir una ventana que contiene una pluralidad de palabras digitales alrededor de una palabra que ha de ser filtrada; medios (18) para suministrar bits desde po- siciones correspondientes de bits de palabras en dicha ventana a respectivos medios (20) de suma y de umbral; pudiendo ser activados dichos medios (20) de suma y de umbral para que emitan un bit de sa- lida preestablecido si la suma de los bits aplicados a dichos medios de suma y de umbral excede un umbral preestablecido; y medios de salida para emitir una palabra digital correspondiente a un resultado genérico o a una salida de filtro representada por las salidas de dichos medios de suma y de umbral.
