Abstract

LA INTERFASE ESTA CONSTITUIDA POR UN OSCILADOR DE TIPO MULTIVIBRADOR AESTABLE DE ANILLO QUE COMPRENDE UN NUMERO IMPAR DE ELEMENTOS INVERSORES (2A...2N). LAS ENTRADAS DE ALIMENTACION (3,4) DE LOS ELEMENTOS INVERSORES CONSTITUYEN LAS ENTRADAS FUNCIONALES DE INTERFASE. LA SEÑAL DE SALIDA DEL OSCILADOR ES UNA SEÑAL CONTINUA DESDE EL MOMENTO EN QUE UNA DE LAS ENTRADAS NO ES ALIMENTADA CORRECTAMENTE Y LA INTERFASE TIENE LA PROPIEDAD DE SER DE ALTA SEGURIDAD DE FUNCIONAMIENTO RESPECTO DEL CONJUNTO DE LAS AVERIAS QUE PUEDEN PRODUCIRSE EN SU SENO. LA INTERFASE PUEDE UTILIZARSE COMO ELEMENTO DE BASE DE UN MODULO DE VOTO.
