Abstract

Il metodo comprende lo stabilire, in un segnale analogico SA, diverse aree di misura TA, TB, TC, basate sulle variazioni del gradiente di detto segnale, per realizzare un segnale digitale ST in accordo a tali variazioni.A tal fine, è usato un circuito elettronico comprendente un amplificatore operazionale 1, con un ritardatore di tempo 2 che compara il segnale analogico SA con lo stesso segnale, ritardato in modo insignificante rispetto alla durata del segnale.
