Abstract
Un circuito para proteger los datos transmitidos, en donde los datos codificados se comprueban cíclicamente para detectar errores mediante una comprobación redundante que se realiza dividiendo las palabras en código en un registro de conversión y realimentación cuyo estado es interrogado por una puerta, caracterizado porque incluye una segunda puerta (G2) en paralelo con la puerta de interrogación (G1), y porque los potenciales que aparecen en las salidas de la puerta se aplican a un circuito de comparación (VS).
